摘　　要：利用熔融接枝法制备了马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH),探讨了各个因素对POE-g-MAH接枝率和熔体流动速率(MFR)的影响,并得出了最佳配方、最佳工艺条件。将POE与接枝产物POE-g-MAH同时作为弹性体改性PA6时,体系的缺口冲击强度较纯尼龙提高近9倍,而其他力学性能改变不大。,Maleic anhydride grafting ethylene-octene copolymer （POE-g-MAH） was pre- pared by melt grafting. The kinds of factors on the graft ratio of POE-g-MAH and MFR were studied. The optimum contents of MAH and DCP and the best technical condition were determined. The impact strength was improved about 9 times while the other mechanical properties fluctuate little when PA6 was modified by POE and POE-g-MAH simultaneous.
