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。

Abstract: 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.

Key words: PE100, PA6, HDPE-g-MAH, POE-g-MAH, heat resistant
