增容聚苯乙烯共混物的研究进展

Research Development of Compatibilized Polystyrene Blends

综述了增容聚苯乙烯与聚乙烯、聚丙烯、聚酰胺共混物的研究进展。不同共混物采用不同的增容剂,可使增容聚苯乙烯共混物改善分散相尺寸、界面相互作用与粘结,达到提高共混物的力学性能的目的。增容效果与增容剂的类型、用量和分子结构有关。

The research development of compatibilized polystyrene blends with polyethylene, polypropylene, polyamide was reviewed. The effect of block and graft copolymers as compatibilizing agents, and reactive compatibilization on the morphology and properties of polystyrene blends was discussed. The size of phase, interfacial interaction and adhesion were improved and the mechanical properties of different polystyrene blends were increased by addition of different kinds of compatibilizing agents. The compatibilizing efficiency depend upon the kinds, the content and molecular structure of compatibilizing agents.
