    • 摘要: 利用丙烯酰胺(AM)和甲基丙烯酰氧乙基三甲基氯化铵(DMC)为原料进行二元共聚,采用复合引发体系合成一种耐高温酸液稠化剂,通过单因素分析法确定最佳反应条件,对合成样品进行红外表征,并对其增黏性能、流变性能等进行评价。结果表明,最佳合成条件为DMC的质量分数15%、引发剂加量为0.4%、聚合温度50°C、聚合时间4 h。合成的稠化剂易溶于酸,增黏效果好,在160°C、170 s^(-1)条件下,质量分数0.8%的稠化剂溶于质量分数20%的盐酸中剪切60 min,黏度保持在30 mPa·s左右,具有较好的耐温性和耐剪切性;与缓蚀剂、铁离子稳定剂、黏土稳定剂等添加剂配伍性较好,形成的稠化酸体系可以有效提高酸液黏度,降低酸岩反应速率,提高酸刻蚀裂缝的穿透深度,为超深井酸压用工作液提供技术支撑。

    • 摘要: Acid-dye dyeable acrylonitrile copolymers with different molecular composition were prepared by using dimethylami -no ethyl methacrylate (DEMA) or methacryloyloxyethyl trimethyl ammonium chloride (DMC) as the third monomer via batch precipitation polymerization in aqueous phase .The structure and properties of the obtained copolymers were characterized by hy-drogen nuclear magnetic resonance spectroscopy , gel permeation chromatography , differential scanning calorimetry , dye up-take test and so on .The results showed that the polymerization process using one-pot initiator feeding method showed the characteristic of "dead-end polymerization", which led to the multimodal molecular weight distribution;the obtained copolymer had the viscosi-ty-average relative molecular mass of 50000-60000, the polydisperity index of 5-10, the monomodal molecular weight distribu-tion and conversion rate up to 70% or so when the polymerization was initiated by semicontinuous process; the glass transition temperature was 101.2°Cwhen the mass fraction of acrylonitrile was 90.3%in the copolymer;the dyeing property of the copoly-mer was related to the third monomer content and the molecular structure; the dye up-take was strongly dependent on the acid number of the dye bath when DEMA was used as the third monomer;the dyeing property of the copolymer was not sensitive to the pH value of the dye bath and remained fairly good with the dye up-take above 95%even in weak acid dyeing bath ( pH value of 5.0) when DMC was used as the third monomer .%分别选择甲基丙烯酸二甲氨乙酯(DEMA)和甲基丙烯酰氧乙基三甲基氯化铵(DMC)作为第三单体,采用间歇法丙烯腈水相沉淀聚合制备不同分子组成的酸性可染腈纶共聚物,通过核磁共振氢谱、凝胶渗透色谱、差示扫描量热、上染率等分析测试对共聚物的结构和性能进行了表征.结果表明:引发剂一锅法投料的聚合过程呈现出"死端聚合"的特点,共聚物相对分子质量分布为多峰分布,而采用引发剂半连续加入的方式,制得的共聚物的黏均相对分子质量为50000~60000,聚合物多分散性指数为5~10,相对分子质量分布为单峰分布,且转化率提高至70%左右;共聚物中丙烯腈质量分数为90.3%时,其玻璃化转变温度为101.2°C;共聚物的染色性能与第三单体含量和分子结构相关,以DEMA为第三单体时,其上染率对染浴酸值依赖性较强,而采用DMC为第三单体时,其染色性能对染浴的pH值不敏感,即使在弱酸性染浴(pH值为5.0)中亦具有良好的染色性能,上染率大于95%.
