摘　　要：采用熔融法制备三元乙丙橡胶接枝马来酸锌(EPDM-g-MAZn)离聚物,并用正交试验设计的方法研究了影响离聚物的各种因素。分析了反应物浓度、实验条件等因素对接枝率的影响规律。正交试验结果表明:当单体(MAZn)为20%,引发剂(DCP)为2%,反应时间为6 min,反应温度为200℃时,离聚物的接枝率最高。EPDM-g-MAZn ionomer was prepared by melting method,and then the influencing factors of ionomer were also researched through orthogonal experiments.The influence law of reactant concentration,experimental conditions and other factors on the grafting ratio were analyzed.The results show that： when the monomer concentration（MAZn） is 20%,the initiator concentration（DCP） is 2%,the reaction time is 6 min and the reaction temperature is 200℃,the EPDM-g-MAZn ionomer has the best grafting ratio.
