摘　　要：采用DSC方法测试了PC/PBT( 70 / 3 0 ,质量分数 )共混体系和在体系中加入PE接枝马来酸酐共混物的玻璃化温度 ,研究了PE接枝马来酸酐对PC/PBT共混体系性能的影响。结果表明 :PE接枝马来酸酐的加入改善了PC/PBT共混体系两相间的相容性 ,而且还起到增韧作用 。It tested both the glass transition temperatures of PC/PBT (70/30, wt%) and PC/PBT/PE-g-MAH blending systems, and studied the influencing effects of PE-g-MAH on the mechanical properties of PC/PBT blends. The results showed that the compatibility between the two phases of PC and PBT was enhanced by adding the PE-g-MAH to PC/PBT blends, and also the compact property of the blends was greatly improved.
