Abstract

With a new compatibilizer CMG7000 and a common compatibilizer for PA/ABS,the ABSMAH and SAN-co-A and SAN-co-B were compared in this paper,the effect of different kinds compatibilizers on the mechanical properties, thermal stability and microstructure of polyamide(PA)/acrylonitrile butadiene-styrene(ABS) alloy were studied.Research showed that: with the addition of 5% CMG7000,the impact toughness of PA/ABS alloy was greatly improved,while its tensile strength and flexural modulus showed no obvious change.The CMG7000 could improve the interface combination between two phases and micro-structure morphology of the blends,because of synergistic effect of its special multi-component system which had higher toughing efficiency.
