悬浮分散剂对苯乙烯/N-苯基马来酰亚胺共聚物颗粒特性的影响

摘要

Styrene/./V-phenylmaleimide copolymer (SMI) was synthesized by a suspension method with AIBN as initiator. The influence of different suspension dispersants on characteristic of SMI resins particles was studied. The characterization of the copolymers was measured by size distribution analysis, SEM and DSC. It was found that the inorganic composite dispersant was the best in this system.%以偶氮二异丁腈( AIBN)为引发剂,采用悬浮聚合的方法合成苯乙烯/N -苯基马来酰亚胺共聚物( SMI).本文着重研究了不同悬浮分散体系对产物颗粒特性以及产物性能的影响.并使用粒度分析、SEM、DSC等手段进行表征,结果发现无机复合分散体系最适合于该悬浮反应.
