摘　　要：用预辐照接枝的方法，制备了弱酸型ＰＰ基离子交换纤维聚丙烯－聚甲基丙烯酸－二乙烯基苯ＰＰ－ｇ－ＰＭＡＡ－ＤＶＢ，研究了接枝反应条件对接枝率的影响，并研究了接枝率与纤维力学性能的关系。在本实验条件下，接枝率一般在７０％左右，纤维断裂强度在２００～３００ＭＰａ。A weak acid type cation exchange fiber PP g PMAA DVB was prepared by means of grafting of methacrylic acid(MAA) onto pre irradiated PP fibers. The effect of reaction conditions on grafting was studied. The relationship between the grafting percentage and mechanical properties was also studied. Under the experimental conditions, the grafting percentage of 70% could be obtained. And breaking strength was in the range of 200￣300 MPa. Elongation at break reached about 10%.
