摘要
将烯烃单体与马来酸酐进行共聚．用所得共聚物进行接枝，引入阴离子表面活性基因，使所得接枝共聚物链上具有羧基、羟基、磺酸基等阴离子活性基因。该接枝共聚物具有良好的保坍性能。
Monomer olefin was copolymerized with maleic anhydride. The copolymer obtaieed was grafted with anionic surfactant groups to form a new polymer with active groups of carboxylic acid,hydroxy and sulfonic acid its chains.The grafted copolymer has good slump loss resistant property.
