以甲基丙烯酰氯、对羟基苯甲酸和二聚或三聚全氟聚醚醇为原料合成了含氟甲基丙烯酸酯单体3a和3b，以甲基丙烯酰氯和二聚或三聚全氟聚醚醇为原料合成了含氟甲基丙烯酸酯单体4a和4b，并与丙烯酸甲酯、丙烯酸正丁酯和丙烯酸羟乙酯共聚，制备了含氟甲基丙烯酸酯乳液PFA1，含三聚全氟聚醚侧链和苯环间隔基的乳液PFA 2具有优异的拒水拒油性能，经PFA 2处理的棉织物对水的接触角为146°，对正十二烷的接触角为120°。
Fluorinated methacrylate monomers 3a and 3b were synthesized by methacryloyl chloride, 4-hydroxybenzoic acid and dimeric or trimeric perfluoropolyether alcohol.Fluorinated methacrylate monomers 4a and 4b were synthesized by methacryloyl chloride and dimeric or trimeric perfluoropolyether alcohol as comparison.The fluorinated methacrylate monomers were copolymerized with methyl acrylate,n-butyl acrylate and 2-hydroxyethyl acrylate to form copolymer emulsions PFA1, PFA2,PFA3 and PFA4 respectively.Emulsion PFA2 containing trimeric perfluoropolyether side chain and phenyl ring as a spacer group achieved excellent water and oil repellency.Cotton fabric treated with PFA2 had contact angles as 146°for water,and 120°for n-dodecane.
