对叔丁基杯芳烃对聚丙烯性能的研究

摘要

采用DSC测定氧化诱导期法研究了对叔丁基杯[n]芳烃(n=4、6、8)对聚丙烯(PP)热稳定性的影响,并研究了对叔丁基杯芳烃对聚丙烯(PP)力学性能和结晶性能的影响.结果表明,一定量对叔丁基杯芳烃可以显著提高PP的热氧稳定性,并且还能起到异相成核作用从而增加PP的结晶度和冲击强度.%The effect of oxidation properties of calixarene/polypropylene (PP) blends on thermal stability were evaluated by DSC.The mechanical properties and the crystallization properties of the blends were also investigated.Experimental results showed that the oxidation properties of PP could be improved byadding a certain amount of calixarene.At the same time, the crystallization rate and impact properties of PP were also increased by the adding of calixarene due to heterogeneous nucleation effect.
