摘　　要：采用甲基丙烯酸聚乙二醇单酯与(甲基)丙烯酸类单体进行共聚,制备了一种水性支链型超分散剂。测试结果表明这种分散剂对颜料的分散性能、稳定性能均优于传统聚合物分散剂,是一种性能优良的新型分散剂。A kind of waterborne branched super - dispersant was synthesized by copolymerization of methacrylate polyglocol monoester and（ methy 1）acrylic acid. Compared with the traditional polymer dispersant, this super- dispersant shows better dispersing capability and stabilization for pigments and is a novel kind of highly efficient dispersant.
