摘要
以Ｓｐａｎ８０ｔｗｅｎ８０为乳化剂（ＨＬＢ＝６４４）、Ｋ２Ｓ２Ｏ８为引发剂、甲苯为油相，研究了丙烯酸—丙烯酰胺反相乳液共聚合反应动力学．通过元素分析求得共聚物组成及单体竞聚率．利用膨胀计法求得共聚合反应动力学方程，水相ｐＨ值及单体配比对聚合反应速率均有显著影响，并对上述结果进行了讨论．
The Kinetics of inverse emulsion copolymerization of acryl acid and acrylamide using span 80Tween 80 mixture as emulsifier(HLB=6 44),K 2S 2O 8 as initiator and toluene as continuous phase was studied.The monomer reactivity ratios and the stoichiometry of copolymer was obtained by elements analysis.A Kinetics expression was given.The aqueous pH and monomer ratio affect the copolymerization rate markedly.These results were discussed in detail.
