以甲基丙烯酸甲酯（MMA）、丙烯酸丁酯（BA）、丙烯酸六氟丁酯（HFA）为原料，通过细乳液聚合法制备出了水性聚丙烯酸酯细乳液．研究了 H FA 用量对单体转化率、细乳液粒径、成膜吸水率、接触角及涂饰革样卫生性能和干湿擦牢度的影响．结果表明：随着 HFA用量的增加，单体转化率保持在97％左右，细乳液粒径逐渐增大，接触角先增大后保持不变；成膜的吸水率在HFA用量为0．5％时最低，为6．84％；HFA 的引入在不影响革样卫生性能的同时可使干湿摩擦牢度均提高1级．

A waterborne polyacrylate miniemulsion was synthesized by miniemulsion polymer‐ization with methyl methacrylate ,butyl acrylate ,hexafluorobutyl acrylate (HFA) .The effect of HFA content on monomer conversion rate ,particle size ,water absorption ,contact angle , sanitation properties and rubbing fastness of coated leather were studied and the results indi‐cate that the properties of polyacrylate miniemulsion were improved by HFA .As the HFA content increased ,monomer conversion rate remained at around 97% ,latex particle size in‐creased ,contact angle increased and then kept constant .The film water absorption reached the minimum 6 .84% when the HFA content was 0 .5% .The dry and wet fastnesses of the coated leather were improved by 1 degree without compromising the sanitation properties .
