4种终止剂在悬浮法聚氯乙烯生产中的应用对比

Application comparison of four terminators in suspension PVC production

从终止剂的物化性能、用量和使用成本,聚氯乙烯树脂的热稳定性,离心母液COD以及对聚合引发体系的影响等多个角度对4种终止剂(水溶型、油溶型、乳液型和悬浮型)进行了对比,以期为聚氯乙烯生产单位选择终止剂提供参考。

Four kinds of terminators(water-soluble,oil-soluble,emulsion-type and suspensiontype)were compared in aspects such as physical and chemical properties,dosage,use cost,thermal stability of PVC resin,COD of centrifugal mother liquor,and the influence on polymerization initiation system,.in order to provide reference for PVC manufacturers to choose termination agent.
