Abstract

Abstract:

PC/ABS alloy was prepared through melt blending process by using PC,ABS and different kinds of compatibilizing agents. The structure and mechanical properties were characterized by DSC and normal mechanical measurement methods. The results show that PC/ABS belongs to partially-compatible system, the compatibility and mechanical properties could be improved when compatibilizing agents ABS-g-MAH and PE-g-MAH were added to the blending system. The modification effect of ABS-g-MAH is better than that of PE-g-MAH. The reason is that the similar molecular structure of ABS-g-MAH and PC/ABS alloy, at the same time, the interface adhesion could be improved through ester exchange reaction between acid anhydride in ABS-g-MAH and PC.

摘要： 采用熔融共混工艺路线,选用合适的PC,ABS和相容剂,制备了PC/ABS合金材料,通过DSC和力学性能测试对所得到的合金材料进行了结构及力学性能表征。结果表明,PC 与ABS为部分相容体系,加入相容剂ABS-g-MAH 和PE-g-MAH,可以改善合金的相容性,从而提高了合金材料的综合力学性能。ABS-g-
MAH 的改性效果要好于PE-g-MAH,ABS-g-MAH 中的ABS部分与PC/ABS合金中的ABS相具有相似结构,并且酸酐基团可以与PC发生酯交换反应,因而可以更好的融入PC相中,提高了两相的界面黏结力而导致力学性能的提高。
