摘　　要：通过熔融共混法制备了马来酸酐接枝(乙烯/丙烯/二烯)共聚物(EPDM-g-MAH)增容的尼龙6/(丙烯腈/丁二烯/苯乙烯)共聚物(PA6/ABS)合金,考察了PA6/ABS配比和EPDM-g-MAH用量对PA6/ABS合金力学性能、热学性能及吸湿状态的影响;观察了PA6/ABS合金表面微观结构。结果表明,EPDM-g-MAH是PA6/ABS合金的有效增容剂,当PA6/ABS/EPDM-g-MAH质量比为90/10/10时合金综合性能最好,尤其能显著地改善材料的冲击韧性、耐热性,降低吸水率。PA6/ABS alloy was prepared with EPDM-g-MAH as the compatilizer by melting crossblend. The effects of PA6/ ABS composition ratio and EPDM-g-MAH content on the mechanical properties, thermodynamics properties and water absorption of the PA6/ABS alloy were investigated. The surface micro-structure of the PA6/ABS alloy was studied. The results indicated that EPDM-g- MAH was an effective compatilizer for PA6/ABS alloy, the alloy possessed the best comprehensive property when the mass ratio of PA6/ABS/EPDM-g-MAH was 90： 10： 10, especially on impact toughness, heat distortion temperature and water absorption of the alloy.
