摘　　要：研究了聚氯乙烯(PVC)在增塑剂邻苯二甲酸二辛酯(DOP)存在的情况下,以二苯甲酮(BP)为光敏剂、三丙烯酸三羟甲基丙烷酯(TMPTA)为交联剂的紫外光辐照交联。实验证明:光敏剂对交联有着显著的影响;经过辐照,可大幅度提高PVC制品的硬度及拉伸强度。The ultra-violet light radiation crosslinking of PVC with disoctyl phthalete (DOP) as plasticizer, benzophenone (BP) as photoinitiator and trimethylopropanetriacylate (TMPTA) as crosslinking agent was investigated. The experimental results showed that the photosensitizer could obviously affect the crosslinking process. The hardness and tensile strength of PVC products could be improved by ultra -violet light radiation.
