悬浮法PVC树脂颗粒形态的影响因素

Influencing factors of particle morphology of PVC resin prepared by suspension method

分析了悬浮法PVC树脂颗粒形态的影响因素:聚合釜搅拌、分散剂、体系氧含量、转化率、聚合温度、水油比、引发剂、pH值等,提出了相应的控制措施。

The influencing factors of particle morphology of suspension PVC resin were analyzed,such as polymerizer agitator,dispersant,oxygen content of system,conversion rate,polymerization tem-perature,water and oil ratio,initiator,pH value,etc.,and corresponding control measures were putforward.
