| 摘 要： | 通过接枝二乙基二硫代氨基甲酸钠（铜试剂），在PVC分子链上引入光敏基团，从而在紫外光照射下，PVC分子间可发生交联反应形成交联产物。实验研究铜试剂用量、接枝反应温度与时间以及紫外光辐照时间对PVC的凝胶含量、力学性能及耐热性的影响，从而确定最佳交联条件。在此条件下可得到凝胶含量超过83％的交联产物。

| Abstract: | Light sensitive group was introduced into PVC molecular chains by PVC grafted by diethyldithiocarbanate(copper reagent).In the radiation of ultra violet light,cross linking reaction took place among PVC molecular chains and cross linking PVC was obtained.The effects of the dosages of the copper reagent,the temperature and time of grafting reaction and the time of ultra violet light radiation on gel content,mechanical properties and hot resistant properties of cross linking PVC were investigated and the optimum cross linking condition was found out.In this condition,PVC cross linking product which contains more than 83 percent gel content was obtained. |
