摘　　要：通过调整复合引发剂配比、链转移剂用量,筛选分散剂,选用复合热稳定剂等进一步优化超低聚合度PVC的配方,制得"鱼眼"数少、质量好的聚合度为500、600的PVC。The formula of PVC with ultra low polymerization degree was optimized through adjusting the ratio of compound initiators and the dosage of chain transfer agent,and selecting dispersing aids and compound heat stabilizers.Thus,PVC resins with polymerization degree of 500 and 600 were obtained with less fish eyes and good quality.
