摘　　要：以丙烯酸、丙烯酰胺和丙烯酸丁酯为单体,采用瞬时聚合法合成了高分子表面活性剂。表面活性研究表明,制备的高分子表面活性剂有良好的表面活性,表面张力可低至42 mN/m。红外光谱表明,产物没有发生交联,黏度法测定产物的分子量为2×104～4×104。Polymeric surfactants were prepared by instant polymerization,using acrylic acid,acrylamide and butyl acrylate as monomers.Properties and structures were characterized by FT-IR and viscosimetry.The results showed that there was no crosslink structure in polymeric surfactants and the polymeric surfactants had good surface activities,with the lowest surface tension of 42 mN/m and molecular weight of 2×104～4×104.
