摘　　要：分别以高密度聚乙烯接枝马来酸酐(HDPE-g-MAH)和乙烯-辛烯共聚物接枝马来酸酐(POE-g-MAH)作为相容剂,通过熔融挤出法对PE100/PA6共混物进行共混改性。研究了两种相容剂的用量对共混物力学性能、热性能和微观结构的影响。结果表明:HDPE-g-MAH与POE-g-MAH相比,都使体系发生反应性增容的同时,对共混物的结晶性更为有利,使得PE100/PA6/HDPE-g-MAH的综合性能更好,更适合作为PE100耐热改性时的增容剂。PE100/PA6 blend alloys were prepared via melting extrusion with high-density polyethylene grafted with maleic anhydride（HDPE-g-MAH） and ethylene-octene copolymer grafted with maleic anhydride（POE-g-MAH） as two compatibilizers separately.The effects of two compatibilizer contents on mechanical properties,thermal properties,and microstructure of the blends were investigated.The results showed that both compatibilizer addition caused reactive compatibilization,compared to POE-g-MAH,HDPE-g-MAH is more beneficial to the crystalline,comprehensive performance,more suitable for PE100/PA6 in heat resistant modification.
