摘　　要：制备了低密度聚乙烯(LDPE)熔融接枝马来酸酐(MAH)黏性树脂,用红外光谱表征了接枝反应的存在,并对其接枝率及尼龙6(PA6)膜的粘结性能进行研究。结果表明:当MAH的质量分数为0.8%、过氧化苯甲酰(BPO)的质量分数为0.08%时,所得共聚物的接枝率达到0.9%,凝胶含量为7.6%,对PA6膜的平均剥离强度达到54.6 N/cm。Low density polyethylene grafted maleic anhydride （MAH） adhesive resin was prepared. The IR spectra showed that MAH was successfully grafted onto LDPE backbone. The effects on grafting ratio and adhesive property with nylon 6 （PA6） film were studied. The results showed that when the content of MAH and BPO reached 0.8% and 0.08% , the graft- ing ratio reached 0.9% , the gel content reached 7.6% and the peel strength with PA6 film reached 54.6 N/cm.
