摘要
用ＩＲ、ＤＳＣ、ＧＰＣ研究了侧基含有过氧键的活性聚苯乙烯（ＲＰＳ）与聚乙烯（ＰＥ）之间的反应，用ＳＥＭ观察了共混物的断面形态。结果表明，ＲＰＳ／ＰＥ共混反应中生成ＰＳ－ｇ－ＰＥ，对ＰＥ／ＰＳ共混物具有增容作用，提高了共混物的力学性能。
Using IR, DSC, GPC measurements, the reaction between RPS with the peroxy group as a pendant group along polystyrenic backbone and LDPE was studied, the morphology of blends was investigated by SEM also. The results show: the RPS/PE blends have compatibilizing effect to PS/PE blends, and improve their mechanical properties.
