摘　　要：研究采用半连续种子乳液聚合法,以十三氟辛基三乙氧基硅烷(G607)为含氟单体,甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)为主要聚合单体,合成含氟聚丙烯酸酯乳液。重点考察了乳液聚合过程中核/壳质量比、含氟单体用量、交联剂用量对含氟聚丙烯酸酯乳胶膜疏水性能的影响。结果表明:当核/壳质量比为70/30、含氟单体用量为10%、交联剂用量为3%时,所得乳胶膜的疏水性能较优,将其喷涂于皮革表面,可赋予皮革良好的疏水效果。The fluorinated polyacrylate latex was synthesized by semi-continuous seeded emulsion polymerization with methyl methacrylate （ MMA）, butyl acrylate （BA） as main monomers, tridecafluorooctyltriethoxysilane （ G607 ） as fluorine-containing mon-omer. The effects of the core/shell ratio, the dosages of G607 and crosslinking agent on the hydrophobicity of fluorinated polyacry-late latex were investigated. The results show that the hydrophobic properties of fluorinated polyacrylate latex is the best when the core/shell ratio is 70/30, the dosages of G607 and crosslinking agent are 10% and 3 %, respectively. The leather finished by fluori- nated polyacrylate latex shows excellent hydrophobic properties.
