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
