摘要
合成了不同马来酸酐含量的苯乙烯与马来酸酐共聚物Ｐ（Ｓｔ－ＭＡＨ），添加到ＰＣ／ＰＳ共混体系中，可增加二者的相容性。在共混体系中，ＰＣ相Ｔｇ变化不大，而ＰＳ相Ｔｇ升高，升高的幅度与共聚物中ＭＡＨ含量有关，含ＭＡＨ１２．８％时效果最好；也与ＰＣ／ＰＳ共混体系中ＰＳ含量有关，ＰＳ较少时升幅较大。
The copolymers P(St MAH) of styrene and different contents of maleic anhydride were synthesized and investigated by IR and DSC It has been shown that the T g of P(St MAH) increases with increasing MAH contents The compatibility of P(St MAH) with PC/PS blends were studied by DSC It has been found that the compatibility of PC phase with PS phase improves after the addition of the PC/PS blend system The T g of PS increases while no obvious change is observed in the case of PC The best effect corresponds to a MAH content of 2 8% It also depends on the content of PS in the blend,a higher increase in compatibility corresponds to a lesser PS content
