中文摘要：
采用氯化原位接枝的方法合成了以高密度聚乙烯（HDPE）为骨架、马来酸酐（MAH）为支链的接枝聚合物，反应中不需要加入任何引发剂。傅立叶红外光谱（FTIR）分析证明了该方法对HDPE改性的可行性。探讨了影响接枝聚合物力学性能的因素及变化规律。结果表明，接枝反应温度、接枝率以及MAH单体的加入量对MAH氯化接枝HDPE（HDPE-cg-MAH）的力学性能有很大的影响。
英文摘要：
A grafting copolymer （HDPE-cg-MAH）, composed of maleic anhydride （MAH） as branched chains and HDPE as backbone, was synthesized by in-situ chlorinating graft copolymerization. No initiator was added in the system. The graft polymer was characterized by FTIR. The feasibility of grafting MAH onto HDPE was proved. The influential factors of mechanical properties and their variation regularity were discussed. The testing results show that the mechanical properties of HDPE-cg-MAH are influenced by reaction temperature, graft degree and the additional amount of MAH greatly.
