本实验室采用乳液聚合技术成功制备了含有不同带反应基团的单体的含氟共聚物乳液。测量并比较经氟化防水剂处理的织物在洗涤 30 次和 50 次后的防水性和耐久性。实际上，共聚后含有封端异氰酸酯或其他反应性基团的共聚单体的组合会增加拒水性的持久性。此外，封端异氰酸酯交联剂（Jintexguard FCN）确实也显着提高了耐用性。这清楚地表明，由氟化丙烯酸酯、甲基丙烯酸环己酯和甲基丙烯酸3-氯-2-羟基丙酯(Topolene M)与含有封端异氰酸酯基团的单体(Jintexan BIA)反应制备的共聚物乳液表现出非常好的耐久性。更重要的是，这种共聚物与 Jintexguard FCN 的组合将显着提供优异的防水性和 50 次洗涤后的耐用性。 © 2007 Wiley periodicals, Inc.

The fluorinated copolymer emulsions containing different monomers with the reactive groups were successfully prepared at our lab, using emulsion polymerization technique. The water repellency and the durability for the fabrics treated by fluorinated water repellents after 30 and 50 washes were measured and compared. Actually, the combination of the comonomers containing blocked isocyanate or other reactive groups after copolymerization would increase the durability of the water repellency. In addition, the blocked isocyanate crosslinking agent (Jintexguard FCN) does, indeed, substantially increase the durability also. It clearly indicates that the copolymer emulsion prepared by the reaction of fluorinated acrylate, cyclohexyl methacrylate, and 3-chloro-2-hydroxy-propyl methacrylate(Topolene M) with monomers containing blocked isocyanate group(Jintexan BIA) showed very good durability. More importantly, the combination of this copolymer and Jintexguard FCN will significantly provide excellent water repellency and durability after 50 washes. © 2007 Wiley Periodicals, Inc.
