淀粉-丙烯酰胺反相乳液聚合

摘要

采用反相乳液聚合,以淀粉、丙烯酰胺为原料,过硫酸铵为引发剂制备了淀粉丙烯酰胺聚合物.实验表明,最佳反应条件为:引发剂加量为单体总量的0.1％,油水体积比为1∶1,反应温度为60℃,反应时间为4h.淀粉丙烯酰胺聚合物的除浊率可达89％,吸水率达350％.%The polymer was prepared by inverse emulsion polymerization, starch and acrylamide as raw materials. Ammonium persulfate as the initiator prepared starch-acrylamide polymer. The experimental showed that the optimum reaction conditions were as follows:mass ratio of initiator to monomer is 0. 1% , oil to water volume ratio is 1:1, reaction temperature is 60 ℃ ,and reaction time is 4 h. The starch-acrylamide polymer turbidity removal rate up to 89% ,and water absorption up to 350%.
