中文摘要：
以甲基丙烯酸单封端聚乙二醇大分子单体（PEG）为反应性分散稳定剂、N，N’-亚甲基双丙烯酰胺（Bis—A）为交联剂、甲基丙烯酸（MAA）与己内酯改性丙烯酸酯（FA3）为单体，在醇水介质中进行分散共聚反应，得到了两亲性共聚物微凝胶。用激光光散射（LLS）测定了微凝胶的粒径，发现其粒径在纳米尺度范围，且该微凝胶具有pH响应性。将两亲性共聚物微凝胶加入保湿霜，可以提高其保湿性能。
英文摘要：
Amphiphilic microgels were prepared by dispersive copolymerization of acrylate as monomers in ethanol - water solvent, with poly - ethylene glycol （ reactive dispersant and N, N＇ - methylenebisacrylamide （Bis - A） as cross - methacrylic acid and caprolactone modified ending capped with linking agent. The methacrylic acid） as size of the micmgel particles was characterized by laser light scattering （LLS）. It was found that the radius of the microgels were at nanometer range, and the microgels show pH response characteristics. Addition of amphiphilic microgels into the moisturizing cream, the moisturizing performance of the product is improved.
