摘　　要：研究了硬聚氯乙烯(RPVC)熔体凝胶化的规律,探究了增韧树脂冲击强度与凝胶化的相关性,阐明了增韧效果的好坏取决于增韧剂与树脂分子间能否形成均匀稳定的熔体网络。试验结果说明橡塑型增韧剂的增韧效应优越。The regularity of gel on RPVC melt was studied, the relation of impact strength-gelatination on toughening resin was researched, toughening effect depends on plasticizers which whether results stable-homogeneous resin melt network with macromolecular chain was demonstrated. Tests indicate the plasticigers of plastic-rubber is of excellent toughening efficiency.
