摘 要:以衣康酸(IA)和丙烯酸(AA)为原料,采用水溶液聚合的工艺路线,合成了AA—IA共聚物钠盐,研究了单体配比、引发剂用量、反应温度、反应时间等因素对AA—IA共聚物钠盐的合成及助洗性能的影响。确定了较佳的工艺条件:IA占总单体的摩尔分数为22%,过硫酸铵用量为总单体质量的6.67%,反应温度80℃~85℃,丙烯酸和过硫酸铵的滴加时间为2.5h,保温时间为3.5h,总反应时间为6h。The preparation of itaconic - acrylic acid copotymer sodium salt ( AA - Co - IA) with itaconic acid and acrylic acid as starting materials through aqueous solution polymerization process was studied. Effects of monomer ratio, initiator dosage, reaction temperature and reaction time on synthesis of AA - Co - IA and its properties for the use as detergent builder were investigated. The optimum technical conditions were confirmed as : mole percent of itaconic acid is 22% of all monomers ; reaction temperature is 80 ℃ - 85℃ ; the dosage of ammonium persulfate is 6.67% of the weight of all monomers; the addition of acrylic acid and ammonium persulfate takes 2.5 h. Time for keeping of reaction temperature is 6 h.
