| 摘 要： | 用2种分子量不同的苯乙烯-(乙烯/丁烯)-苯乙烯三嵌段共聚物(SEBS)和一种苯乙烯-b-乙烯/丁烯((SEB)两嵌段共聚物为增容剂,对高密度聚乙烯(HDPE)/间规聚苯乙烯(sPS),共混物进行增容.采用扫描电镜(SEM)及拉伸试验研究了增容剂的分子量及结构对共混物形态结构及力学性能的影响.结果表明:3种增容剂SEBS (SEB)均可有效地降低sPS分散相的尺寸并增加HDPE/sPS共混物的界面强度,从而提高其力学性能.sPS的掺入可以显著提高HDPE的耐热性能.

| Abstract: | Two triblock copolymers of poly styrene-b-(ethylene-co-butylene)-b-styrene](SEBS)of different molecular weights and one diblock copolymer of poly styrene-b-(ethylene-co-butylene)(SEB)were used to com-patibilize high density polyethylene/syndiotactic polystyrene(HDPE/sPS)blend.Morphology observation showed that phase size of the dispersed sPS particles was significantly reduced on addition of all the three copolymers and the interfacial adhesion between the two phases was dramatically enhanced.Tensile stren... |
