摘　　要：本文以丙烯酸、甲基丙烯酸甲酯、甲基丙烯酸、丙烯酸丁酯为单体,以偶氮二异丁腈为引发剂,以异丙醇为溶剂,采用溶液聚合法合成了水溶性丙烯酸树脂。通过研究溶剂与单体的配比、滴加时间、保温时间对树脂水溶性和粘度性能的影响,确立了水溶性丙烯酸树脂的最佳合成配方。在配方条件下制得的树脂为淡黄色透明液体,水溶性好。The water-soluble acrylic resin was synthesized with the solution polymerization.And it was pre-pared via solution polymerization which takes acrylic acid,butyl acrylate,methacrylic acid,methyl methacrylate as the monomers,takes azobisisobutyronitrile as the initiator and takes isopropyl al-cohol as the solvent.By discussing solvent and monomer’s allocated proportion,instilment time,heat preservation time to the resin’s performance influence,such as the water-solubility,viscosity,the best formula of synthesis water-soluble acrylic resin for water-based coatings was obtained.The resin prepared under the condition of formula is light yellow transparent liquid with good watersolubility.
