摘　　要：采用熔融法制备乙烯-1-辛烯共聚物(POE)接枝甲基丙烯酸环氧丙酯(GMA),利用红外光谱对其结构进行表征。考察了GMA和过氧化二异丙苯(DCP)用量以及反应温度和反应时间对接枝率的影响,结果表明,GMA用量增加,接枝宰逐渐增大,熔体流动速率逐渐下降；隨着引发剂用量的增加,接技率也隨之增加；同时隨著反应温度和反应时间的变化,接枝率随之变化。然后采用熔融共混法制备了纳米CaCO_3／POE-g-GMA／PA66复合材科,研究了该体系的力学性能,结果表明,纳米CaCO_3和POE-g-GMA对PA66具有一定的增韧作用。It prepared glycidyl methacrylate （GMA） grafted ethylene-1-octene （POE） by means of melting method, and characterized its structure by making use of IR spectrum, It investigated the influencing effects of the content of GMA and DCP, reaction temperature and reacUon time on the graft ratio. The results showed that the graft ratio increases with the increasing content of GMA and DCP, but the MFR decreases gradually; the graft ratio changes with the change of reaction temperature and reaction time. It also prepared the nano-CaCO3/POE-g-GMA/PA66 composites by means of metting blend method, and studied the mechanical properties of the system. The results showed that nano-CaCO3 and POE-g-GMA have some toughening effect on PA66.
