【摘要】 从影响因素、晶态变化、界面张力和相容性等方面综述了国内外关于聚丙烯 /聚苯乙烯共混物形态的研究进展。聚丙烯 /聚苯乙烯共混物的相形态受多种因素的影响 ,其中混合比例、黏度和界面张力为最关键的因素 ,影响着共混物的热性能和结晶性能 ,从而导致相态的各种变化。提出今后应以相容剂研究和相态控制理论研究为重点更多还原

【Abstract】 The research progress in morphology of Polypropylene and Polystyrene blends (PP/PS) is reviewed,from the view of effects, crystal behavior, interfacial tension and compatibility and so on. Composition, viscosity and interfacial tension are the most important effects that affect blends’ thermodynamic properties and crystal properties consequently change morphology of PP/PS blends. Theories on compatibilizer application and morphology control should be study more in the future.更多还原
