【摘要】 以马来酸酐作为反应单体 ,在隔氧的条件下 ,以BPO为引发剂 ,采用溶液接枝的方法在聚乙烯蜡上接枝马来酸酐 .考察了不同反应时间、不同马来酸酐浓度对接枝率的影响 ,对同等条件下聚乙烯蜡与聚丙烯蜡的接枝率进行比较 .实验以马来酸酐接枝聚乙烯蜡为原料合成了聚乙烯 聚乙二醇单甲醚接枝物 ,采用化学滴定法对聚合物的接枝率进行测定 ,同时利用红外光谱进行表征更多还原

【Abstract】 The copolymerization of polar monomer MA gafting on PEw in the presence of nitrogen has been studied.The effects of different reaction conditions were investigated.PEGME was grafted into PEw-g-MA.The grafted polymers were characterized by means of chemical titration nd IR.更多还原
