單純PPS/ABS物理性摻混,其分散相ABS的粒徑較大。而接枝MAH改質的摻合物,其分散相較小, MAH具有反應性官能基,在高分子間扮演著相容劑的角色,藉著化學鍵結的形成,使兩相更緊密的連結在一起。摻合物中PPS不定形態的部分增多,預期耐衝擊強度將得到改善。 The size of dispersed phase of reactive blending of PPS/ABS is smaller than that of simple physical blend. The MAH has reactive functional groups, it plays a role of compatibilization reagent in polymer blends. Due to the performance of amphiphilic copolymer, the interphase adhesion is improved. The amorphous state of PPS increases in the reactive blends, the impact strength will be improved as expectation.
