摘要
采用熔融法制备高密度聚乙烯与马来酸酐接枝物(HDPE-g-MAH),并以此接枝物制备HDPE-g-MAH/PA6共混合金,通过调整引发剂过氧化二异丙苯(DCP)和马来酸酐的用量来控制接枝率,并研究该共混合金的性能与接枝率之间的关系。结果表明:HDPE-g-MAH/PA6共混合金的力学性能、耐热性等均较纯高密度聚乙烯有很大提高,当质量比HDPE∶PA6∶MAH∶DCP为60∶40∶1∶0.3时,共混合金表现出较佳的性能。
Maleie anhydride grafted HDPE （HDPE-g-MAH） and HDPE-g-MAH/PA6 blend alloy were prepared by melt grafting. The grafting degree was controlled by alternating the ratio of maleic anhydride and dieumyl peroxide. The relationship between the properties of HDPE-g-MAH/PA6 blend alloy and the graft ratio of HDPE-g-MAH was studied. The results indicated that the mechanical properties and heat resistance of HDPE-g-MAH/PA6 blend alloy increased compared with pure HDPE. The better properties of the blend alloy were observed when the ratio of HDPE： PA6： MAH： DCP was 60： 40：1 ： 0. 3.
