摘　　要：研究了电解质对丙烯酸酯乳液聚合的影响。加入适量KCi,可提高前期聚合反应速度,降低乳液的粘度,提高乳液的高温稳定性和冻融稳定性。探讨了电解质对乳液性质影响的机理及不同类型乳化剂乳化的乳液的电解质稳定性。The effects of electrolytes on the polymerization ofacrylic emulsion have been studied.The adding ofoptimum amount of KC1 will speed up the reactionrate in early stage of polymerization,lower the vis-cosity of emulsion and increase the high tempera-ture and freez-thaw stability.The mechanism of ef-feet of electrolytes on emulsion properties and thestability of emulsion with various emulsifiers toelectrolytes have been discussed.
