摘要: 研究了亲水性单体AA和引发剂K2S2O8用量对三元共聚物(MMA/BA/AA)无皂乳液(pH=8)的电解质稳定性、冻融稳定性和机械稳定性的影响。当乳液电解质稳定性最好时存在AA和K2S2O8用量最佳值,而乳液的机械稳定性则随AA和K2S2O8用量增大而迅速提高。乳液中加入丙酮可以改善其稳定性。Abstract: The effects of the hydrophilic monomer AA and initiator K 2S 2O 8 on the electrolyte stability, freeze thaw stability and mechanical stability for the copolymer(MMA/BA/AA) soap free emulsion(pH=8)have been studied. There existed the optimum feed amou
