| 摘 要： | 讨论了不同第三组分和不同种聚乙烯对以聚苯乙烯为基质的ＰＳ／ＰＥ共混体系结构和性能的影响，发现苯乙烯－丁二烯－苯乙烯嵌段共聚物和苯乙烯－氢化丁二烯－苯乙烯嵌段共聚物作为第三组分对ＰＳ／ＰＥ共混体系均具有增容作用，用ＳＢＳ的效果比ＳＥＢＳ好，而ＳＢＳ的结构对增韧效果的影响不大。在ＳＢＳ存在下，ＬＬＤＰＥ对ＰＳ增韧效果最好，ＨＤＰＥ次之，ＬＤＰＥ最差。

| Abstract: | The influences of different third components and the types of polyethylene (PE) on the structures and properties of polystyrene/polyethylene (PS/PE) blends, PS taken as matrix, have been studied in this paper. Both styrene - butadiene - styrene copolymer (SBS) and styrene- hydrogenated butadiene -styrene copolymer (SEBS) could be used as compatibilizers for PS/PE blends. The effectiveness of SBS, either linear or radical , was better than that of SEBS. In the presence of SBS , linear low-density polyethylene (LLDPE) was the best toughening agent for the blend, high -density polyethylene (HDPE) came second and low- density polyethylene (LDPE) the third. |
