摘　　要：以α-巯基乙醇为链转移剂,在50 L聚合釜试验生产超低聚合度PVC树脂。考察了链转移剂、分散剂、引发剂的用量及配比对聚合反应及产品性能的影响,并在14 m^3聚合釜上进行了中试生产。At presence of ot-mercapto ethanol as a chain transfer agent, PVC with ultra-low polymerization degree was prepared in a 50-L polymerizer. The effects of addition amount and proportion of chain transfer agent, dispersant and initiator on polymerization reaction and product properties were investigated. Pilot production was carried out in a 14-m^3 polymerizer.
