  • 摘要：Copolymerization of ethylene and propylene was carried out in slurry by using TiCl4/MgCl2 as catalyst. The influence of polymerization conditions on the copolymerization behavior and the chain structure of ethylene-propylene copolymers were studied. Using triethylaluminum/triisobutylalurninum(TiBA) mixture as cocatalyst, the length and amount of long polypropylene (PP) block increased, however, the amount of long polyethylene (PE ) block decreased with the augmentation of TiBA dosage. External donor with higher steric hindrance could improve the isotacticity of PP, but it was harmful for the formation of long PP block. Properly decreasing the polymerization temperature was beneficial to the formation of long PP block. The amount of long PP block increased with the augmentation of TiBA. Therefore, changing the composition of the cocatalyst, using different external donors or adjusting the polymerization temperature could regulate the chain structure and its distribution of ethylene-propylene copolymer.%以负载型钛系催化剂为主催化剂,采用常压淤浆聚合工艺进行乙烯与丙烯共聚合,考察聚合条件对共聚合行为和产物结构的影响.以三乙基铝/三异丁基铝(TiBA)混合物为助催化剂时,随着TiBA用量增加,共聚物中聚丙烯(PP)链段越来越长,且长PP链段数量越来越多,而长聚乙烯(PE)链段数量逐渐减少；空间位阻大的外给电子体虽然可以提高PP的规整度,但不利于形成长PP链段；适当降低聚合温度更有利于形成长PP链段；产物中嵌段共聚物的含量随TiBA用量的增加而提高.所以,改变助催化剂的组成、使用不同的外给电子体或调节聚合温度都可以调控乙烯-丙烯共聚物的链结构及其分布.

  • 摘要：A series of aliphatic-aromatic copolyesters poly (butylene adipate-co-butylene terephthalate) with different composition were synthesized via condensation reaction of 1,4-butanediol, adipic acid and dimethyl terephthalate in the catalysis of rare earth catalyst. The biodegradation behavior of the copolyesters with aromatic molar contents varying from 40% to 60% were investigated via compost by using changes in mass loss rate, mass loss per area and relative molecular mass as indicators. The variations in the composition and sequence structure of the copolyesters before and after degradation were tested by means of hydrogen nuclear magnetic resonance ( H-NMR). The mode of action of the biodegradation behavior was described. The results show that the copolyesters have excellent biodegradability and mechanical properties by introducing the aromatic polyesters chains in a range of 40%-60% into aliphatic polyesters. The degradability of the copolyesters gets worse with the increase in the content of the aromatic component, and the molar fraction of butylene terephthalate rises and the length of the aromatic segment becomes longer after degradation of the samples.%以1,4-丁二醇、己二酸和对苯二甲酸二甲酯为原料,采用稀土催化剂,合成了不同组成的聚己二酸丁二酯和对苯二甲酸丁二酯的共聚酯.采用堆肥法,以堆肥过程中试样的失重率、单位面积失重和相对分子质量变化作为指标,考察了芳香组分摩尔分数为40％～60％共聚酯的生物降解性,利用核磁共振氢谱测试了降解前后共聚酯组成和序列结构的变化,简述了生物降解行为的作用方式.结果表明:通过在脂肪族聚酯中引入摩尔分数为40％～ 60％的芳香组分,所制共聚酯既具有优异的力学性能,又具有生物降解性；且随着所含芳香组分的增多,共聚酯的生物降解性变差,降解后试样的对苯二甲酸丁二酯组分增加且芳香链段的长度增加.

  • 摘要：Polypropylene(PP) containing high content of β-crystal (β-PP) was prepared with small scale hulk PP process in a polymerization reactor by introducing the P-nucleating agent into the reactor prior to pro-pylene polymerization. Adding small amounts of p-nucleating agent did not decrease the activity of the catalyst greatly, and did not cause substantial effect on the relative molecular mass and its distribution of the PP product. The relative content of β-crystal in the β-PP product could reach over 85% when the mass fraction of the nucleating agent was 0.08%-0.12% according to the results of wide angle X-ray diffraction (WAXD). Differential scanning calorimetry (DSC) analysis and mechanical properties test revealed that the crystallization rate of the P-PP was much higher than that of conventional PP without β-nucleating agent, and the β-PP had excellent toughness.%利用小本体聚丙烯(PP)聚合装置及技术,将β成核剂于丙烯聚合前加入聚合釜中,实现了具有较高β晶含量PP的釜内在线制备.当β成核剂含量较低时,催化剂活性无显著降低,PP的相对分子质量及其分布也变化不大.当成核剂质量分数在0.08％～0.12％时,利用广角X射线衍射测试的PP中β晶的相对含量可达85％.差示扫描量热法分析及力学性能测试表明:β晶型PP的结晶速率明显高于不含β成核剂的普通PP,且具有良好的韧性.

The results show that the polymerization rate can increase by raising polymerization temperature during period of the pressure drop, and thermal stability and grain properties of the produced PVC are qualified. In comparison with the PVC resin prepared by isothermal polymerization process, the PVC resin obtained by heterothermal polymerization process has average polymerization degree decreased about 40, the relative molecular mass distribution of the latter increases to 2.15 from 2.05 of the former, and the thermal stability of the latter improves slightly. The processability of the resins so produced is improved owing to its wider relative molecular mass distribution, in the light of which the product can maintain excellent mechanical property by optimizing processing formulation.
  • 摘要：β-polypropylene (PP)ano-CaCO3/polyethylene glycol terephthalate (PET) fiber composites were prepared by means of melt extrusion blending, and the compatibility of the composites was improved by maleic anhydride (MAH) grafted PP (PP-g-MAH). The effects of PET filer, the P-nucleating agent and compatilizer on the mechanical properties, compatibility, and crystallization and melting behavior of the composites were studied. The results indicate that CaCO3 and PET fiber play heterogeneous nucleating role for crystallization of PP and can synergistically induce the formation of β-PP. Adding PET fiber can enhance the composites' rigidity and toughness but damage their tensile property. PP-g-MAH improves the compatibility of PP and PET fiber and facilitates the dispersion of the p-nucleating agent in the composites, resulting in the formation of more β-crystal.%通过熔融挤出共混制备β晶型聚丙烯(PP)/纳米CaCO3/对苯二甲酸乙二酯(PET)纤维复合材料,并用马来酸酐(MAH)接枝PP(PP-g-MAH)改善材料的相容性.研究了PET纤维、β成核剂和相容剂对材料力学性能、相容性和结晶熔融行为的影响.结果表明:CaCO3和PET纤维对PP的结晶具有异相成核作用,能协同诱导形成β晶型PP.加入PET纤维可提高材料的刚性和韧性,但会损坏拉伸性能.PP-g-MAH能改善PP和PET纤维之间的相容性,并能促进成核剂在材料中的分散,形成更多的β晶.

The effects of the mass fraction of sodium hydroxide, reaction temperature and time as well as molar ratio of ECH to BPA on DGEBA yield were investigated. The melting point of DGEBA was 47.5 ℃. The DGEBA yield had a tendency to increase first and then decrease with increasing the mass fraction of sodium hydroxide, molar ratio of ECH to BPA and reaction time, while the yield decreased with the rise in the reaction temperature. The yield of DGEBA reached 80.1% when the molar ratio of ECH to BPA was10 : 1, mass fraction of sodium hydroxide was 30%, reaction temperature was 75 ℃ and reaction time was 170 min.
  • 摘要：使用过氧化二异丙苯降解聚丙烯(PP),熔融法制备降解PP与三元乙丙橡胶(EPDM)共混物,采用广角X射线衍射及差示扫描量热法分析了降解PP/EPDM共混物的晶体结构及非等温结晶动力学.结果发现:PP降解后β晶的(300)晶面消失,导致降解PP及其共混物韧性下降、晶粒的粒径分布变宽；降解PP/EPDM共混物在非等温结晶过程中有明显的快速初级结晶和缓慢的次级结晶过程,降解PP以均相成核的三维球晶方式生长,Avrami指数与Ozawa指数相等,Jeziorny方程和Ozawa方程都可以很好地描述降解PP/EPDM共混物的非等温结晶过程.%The polypropylene (PP) was degraded by using peroxide, and then the blends of degraded PP and ethylene-propylene-diene monomer (EPDM) rubber were prepared via melting process. The crystal structure and non-isothermal crystallization kinetics of the degraded PP/EPDM blends were analyzed by wide angle X-ray diffraction (WAXD) and differential scanning calorimetry (DSC). The results show that crystal face (300) of β -crystal of the degraded PP disappears, as a result, the toughness of the degraded PP and its blends drops and the distribution of the crystal grain diameter becomes wide. The non-isothermal crystallization process of degraded PP/EPDM blends involves obvious fast primary crystallization and slow secondary crystallization process. The degraded PP' crystallites develop in the mode of homogeneously nucleated three-dimensional spheru-lite. Avrami index is nearly equal to Ozawa index, and Jeziorny equation and Ozawa equation can well describe the non-isothermal crystallization process of the degraded PP/EPDM blends.
  • 摘要：Structure and properties of ordinary high impact polystyrene (HIPS) and high gloss HIPS were analyzed by laser particle size analyzer(LS), dynamic mechanical analyzer(DMA) and pyrolysis gas chroma-tography-mass spectrometry(PGC-MS).The results indicate that the high gloss HIPS(HIPS A and HIPS B) has different emphasis on the mechanical properties. The swelling index of the high gloss HIPS is about 11.0 , similar to that of ordinary HIPS, which indicates that the degree of crosslinking of the three samples is similar.

The storage modulus, loss modulus and complex viscosity of PP-g-MAH are higher than those of PPO in high frequency zone.%采用β射线对聚苯醚(PPO)进行预辐照,以产生的PPO大分子过氧化物作引发剂,利用反应挤出接枝法,将功能单体丙烯酸(AA)和马来酸酐(MAH)分别接枝到PPO分子链上,制备AA接枝PPO(PPO-g-AA)和MAH接枝PPO(PPO-g-M AH).接枝率为0.22％的PPO-g-AA,接触角为78.42.；接枝率为0.38％的PPO-g-MAH,接触角为64.28°；接枝率越大,接枝共聚物的润湿性就越好.接枝共聚物与PPO的熔融温度均为262 ℃,接枝率为0.28％的PPO-g-AA与PPO的拉伸强度均为130 MPa,接枝率为0.32％的PPO-g-MAH拉伸强度为128 MPa.在高频区,PP-g-MAH的复数黏度、储能模量以及损耗模量均大于PPO.
  • 摘要：将两种牌号聚乙烯醇(PVA)(PVA1799和PVA0599)混合,然后分别加入甘油/三甘醇、甘油/乙酰胺复合增塑剂对其进行改性.加入复合增塑剂使PVA1799/PVA0599的熔点、结晶度和热分解温度降低；与PVA1799/PVA0599体系相比,改性PVA1799/PVA0599的拉伸强度下降、拉伸断裂应变明显提高；随着PVA0599含量增加,改性PVA1799/PVA0599的熔体流动速率增大；m(PVA1799)/m(PVA0599)为3∶2时,随复合增塑剂用量增加,改性PVA1799/PVA0599的流动性变好；甘油/乙酰胺增塑效果优于甘油/三甘醇；改性PVA1799/PVA0599体系在复合增塑剂为30 phr时可望实现熔融加工.%The authors blended two grades of polyvinyl alcohol (PVA), PVA1799 and PVA0599, and then added glycerin/triethylene glycol or glycerin/acetamide composite plasticizer with the aim of modifying PVA. The melting point, crystallinity and thermal decomposition temperature of the modified PVA1799/PVA0599 reduced with the addition of the composite plasticizers. The modified PVA1799/PVA0599 had decreased tensile strength but significantly increased tensile strain at break in comparison with the PVA1799/PVA0599 blend. The melt flow rate of the modified PVA1799/PVA0599 blend rose with increasing the content of PVA0599. The flowability of the modified PVA1799/PVA0599 became better with the increase in the composite plasticizer content when the mass ratio of PVA 1799 to PVA0599 was 3 : 2. Moreover, the plasticizing effect in glycerin/acetamide composite plasticizer was superior to that of glycerin/triethylene glycol composite plasticizer. When the content of the composite plasticizer is 30 phr, the modified PVA1799/PVA0599 blend seems to realize melt processing.
  • 摘要：综述了聚酰亚胺(PI)与无机粒子复合的研究进展,着重介绍了复合材料的溶胶-凝胶法、插层复合法、机械共混法三种制备方法.将PI与无机材料复合可得到集有机材料和无机材料优异性能于一体的复合材料,改善了传统PI存在的不足.无机粒子改性后的PI在不明显降低材料的热性能和力学性能的同时富集了无机小分子高模量、耐氧化、耐摩擦等性能,优化了材料的性能.引入无机纳米粒子,材料的内部分子堆积、相互作用等发生改变,对气体的选择透过性有很大的改善.改性后的PI具有可控的介电性能、膨胀性能等.%The research progress of polyimide (PI) /inorganic particles composites was reviewed with the emphasis on the methods of preparation, that is, sol-gel method, layer interpolation method and mechanical blending method. Introducing the inorganic articles to the PI matrix could generate composites with excellent properties of both organic and inorganic materials, which remedied the shortages of classic PI materials. PI modified by inorganic particles was endowed with properties including high modulus, oxidation resisting, friction resisting, etc. of inorganic micro-molecule materials but did not display obvious descent in thermal and mechanical properties. As a result, the properties of PI materials were optimized. The molecular structure of PI materials, such as package and interaction of polymer chains, were changed by the introduction of nano-inorganic particles, which contributed to the great improvement in gas permselectivity of PI. The modified PI exhibited controllable dielectric and thermal expansion properties.
  • 摘要：The compatibility and the rheological behavior of melt compounding of bulk acrylonitrile-butadiene-styrene copolymer (ABS) /styrene-N-phenylmaleimide copolymer(SMI) alloy were studied by means of torque rheometer and differential scanning calorimetry ( DSC ) . As a heat-resistant modifier, the highest mass fraction of SMI in the alloy is 60%. The results show that the alloy has only one glass transition temperature, which indicates the good compatibility between ABS and SMI. The melt viscosity during blending process is much higher than that of completely mixed for the high plasticizing temperature of SMI. Increasing blending temperature is helpful to accelerate the dispersion of blending components and shorten the time during which the melt is in high viscosity state.%使用转矩流变仪和差示扫描量热仪研究了本体丙烯腈-丁二烯-苯乙烯共聚物(ABS)/苯乙烯-N-苯基马来酰亚胺共聚物(SMI)合金的相容性及熔融共混过程中的流变特性.SMI作为耐热改性剂,在合金中的质量分数最高为60％.结果表明:ABS和SMI有很好的相容性,合金只有一个玻璃化转变温度.由于SMI塑化温度较高,共混过程中体系黏度远高于完全混匀的熔体黏度.提高共混温度有利于加速共混组分的分散,缩短体系处于高黏度状态的时间.
  • 摘要：A series of straight-chain polyesters were synthesized from aliphatic diols and diesters with different carbon numbers by using lipase N435 as catalyst via multi-stage catalysis. The results show that short-chain diols and diesters are difficult to react with lipase catalysis while long-chain diols and diesters are apt to react with the catalysis of lipase. The polyester having weight average molecular mass (Mw) of 24 816 and relative molecular mass distribution (MW/Mn) of 1.09 can be prepared from the reaction of diethyl adipate and 1,4-butanediol catalyzed by lipase N435. The copolymer with relatively high Mw and narrow MW/Mn can be obtained by lipase-catalyzed copolymerization of diols, diesters and glycerol.%通过多级催化法用脂肪酶N435催化不同碳数脂肪族二醇与二酯反应,合成直链聚酯.结果表明:短链二醇与短链二酯难以被脂肪酶催化发生反应,长链二醇与二酯易被催化发生反应.采用脂肪酶N435催化己二酸二乙酯与1,4-丁二醇反应可以获得重均分子量为24 816,相对分子质量分布为1.09的聚酯.脂肪酶催化二醇、二酯与甘油共聚合可以获得重均分子量较高、相对分子质量分布窄的共聚物.

The content of long stereoregular polypropylene chains is relatively high, and the ethylene sequence distribution is more uniform. The product has excellent performance both in rigidity and toughness.
