摘要
以聚氯乙烯 (PVC)为种子 ,悬浮聚合制备粒度分布均匀的聚苯乙烯 ,研究分散剂的体系、加入量、加入方式和补加时间对粒径分布的影响 .用有机和无机复合分散剂 ,可制得 6～ 2 6目的聚苯乙烯粒子大于 95
The paper dealt with suspension polymerization of styrene with PVC seed. Particularly, the effects on the granular distribution of polystyrene were studied for dispersion system, adding amount, adding type, and adding time in detail. The results shown that the granular distribution more than 95 % with 6～26 mesh was obtained by using the composite dispersing agent of organic and inorganic ones.
