| 摘 要： | 混合顺序对低密度聚乙烯／（苯乙烯－乙烯／丁烯－苯乙烯）三嵌段共聚物／聚苯乙烯共混物的形态有一定的影响。研究结果表明，增容剂先与分散相混合，增容剂集中在分散相，然后与连续相混合，这样增容剂容易迁移到两相界面，具有更好的增容效果。

| Abstract: | The morphology of low, density polyethylene/(styrene-ethylene/butylene-styrene)triblock copolymer/polystyrene blends was found to be dependent on the order of mixing. The distribution of block copolymer in the blends was observed by Transmission Electron Micrcoscopy.The results shown that a masterbatch of minor polymer containing compatibilizer was prepared first; In this way, the compotibilizer was concentrated on the minor polymer.It was easier for the compatibilizer to migrate to the interface and to have a better emulsifying effect when this masterbatch was then compounded wioth matrix polymer. |
