摘　　要：以少量2-丙烯酰胺基-2甲-基丙磺酸的钠盐(AMPS)作为功能性单体,成功制备了一种高稳定性,固含量达50%的甲基丙烯酸甲酯/丙烯酸丁酯[P(MMA/BA)]的无皂乳液。并且对不同单体配比乳液的性能进行研究,总结了单体配比与胶膜吸水性及Tg的关系;同时,讨论了功能性单体AMPS对乳液稳定性、粒子形态的影响。A highstable and high solid content （as high as 50% ） poly （methyl acrylate/butyl acrylate） [ P（MMA/BA） ] emulsiferfree emulsion was made using small guantity of sodium salt of 2-acrylamido-2-methyl propane sulfonic acid（AMPS） as a functional monomer. The properties of the emulsion which is made by different ratio of monomers were studied and the effect of monomer ratio on water absorption and glass transition temperature of the dried emulsion film was also studied. At the same time, the influence of functional monomer AMPS on emulsion stability and emulsion particle morphology was also discussed.
