| 摘 要： | 用乳液聚合方法和交联技术制备了交联聚苯乙烯(XPS)微球，在合成中发现引发剂、乳化剂是影响XPS微球尺寸的主要因素。电镜分析证明XPS微球均匀地分散在聚丙烯基体中，而在热熔融加工中不团聚的必要条件是要有一定的交联度，XPS微球经SBS包覆有利于它的分散；力学性能测试表明分散优良的XPS微球，能真正起到增强、增韧聚丙烯的作用。

| Abstract: | Crosslinked polystyrene microspheres were prepared v ia emulsion polymerization. The effects of the amount of initiator and surfactant on the size of microspheres were investigated. The SEM studies showed that the m icrospheres containing 6 wt % crosslinker and encapsulated with SBS could be fi nely dispersed in PP matrix without coagulation during melting process. The wel l-dispersed microsphere greatly improved the toughness and strength of PP. |
