摘　　要：以甲基丙烯酸六氟丁酯、丙烯酸乙酯、丙烯酸丁酯为主要原料,采用半连续乳液聚合法合成含氟丙烯酸酯共聚物乳液。研究表明:十一烯酸对乳液聚合稳定性有较大改善,随着氟单体含量的增加,聚合稳定性降低,乳胶膜的吸水率降低,接触角增加;当氟单体含量达到12%时,乳胶膜由亲水性转变为疏水性;氟单体的加入提高了革的动态防水性。The fluorinated acrylate copolymers were prepared with ethyl acrylate, butyl acrylate and 2,2,3,4,4,4 -hexaflu-orobutyl methaerylate as main raw materials through semi - continuous emulsion polymerization method. The experiment results indicates that the stability of the fluorinated acylate copolymers is improved by undeeylenic acid, and with the fluoric monomer content increasing, polymerization stability get worse, water absorption of latex films derceases and contact angle increases. The latex film shifts from hydrophilic to hydrophobic when the fluoric monomer content increases to 12%. The dynamic water resistances of finished leather is enhanced with the addition of fluorie monomer.
