【摘要】 用ＨＡＡＫＥ、ＩＲ、ＤＳＣ研究了侧基含有过氧键的活性聚苯乙烯（ＲＰＳ）与线性低密度聚乙烯（ＬＬＤＰＥ）之间的反应，用ＳＥＭ观察了共混物的断面形态，结果表明：共混反应中生成了ＰＳ－ｇ－ＬＬＤＰＥ，对ＬＬＤＰＥ／ＰＳ共混物具有增容作用，提高了共混物的机械性能。更多还原

【Abstract】 Using HAAKE,IR,DSC measurements,we have studied the reaction between RPS and the peroxy group as a pendant group along polystyrenic backbone and LLDPE.The morphology of blends was investigated by SEM also.The results showed that RPS has a compatibilizing effect on PS/LLDPE blends,and improve their mechanical properties.更多还原
