马来酸盐对聚氯乙烯热稳定性的影响
Keywords: 有机高分子材料,聚氯乙烯,热稳定剂,马来酸盐
Abstract:
？合成了一系列不同类型的马来酸盐,研究了马来酸盐对聚氯乙烯(pvc)热稳定性的影响。结果表明,马来酸盐对pvc具有一定程度的稳定作用,其中以马来酸钠和马来酸锌的效果最佳；不同的马来酸盐具有不同的分子结构,而马来酸盐对pvc的稳定化作用与其分子结构和金属阳离子有很大的关系。马来酸盐对pvc的稳定机理：一方面,马来酸盐可取代pvc中的氯原子,或与氯原子络合阻止了pvc脱hcl,或吸收hcl气体防止自身催化降解；另一方面,马来酸盐中的马来酸根与pvc降解后的共轭烯烃发生diels--alder反应。
