A water-absorptive contact lens obtained by saponification of a copolymer composed essentially of (A) from 1 to 30% by weight of a (meth)acrylate polymer having at least one polymerizable group per molecule on an average obtained by copolymerizing (a) an alkyl (meth)acrylate and (b) a monomer having at least two polymerizable groups per molecule, as the main components; (B) from 45 to 95% by weight of a fatty acid vinyl ester; (C) from 0.02 to 10% by weight of a crosslinking agent which is not decomposable by saponification; and (D) from 0.1 to 20% by weight of a crosslinking agent which is decomposable by saponification.
一种通过皂化共聚物而获得的吸水性隐形眼镜,共聚物的主要成分是:(A) 1%至 30%(按重量计)的(甲基)丙烯酸酯聚合物,这种聚合物平均每个分子至少有一个可聚合基团,它是由(a)(甲基)丙烯酸烷基酯和(b)每个分子至少有两个可聚合基团的单体共聚而成;(B) 45%至 95%(按重量计)的脂肪酸乙烯基酯;(C) 0.02%至 10%(按重量计)的不可皂化分解的交联剂;以及(D) 0.1%至 20%(按重量计)的可皂化分解的交联剂。(D) 0.1%至 20%(按重量计)可皂化分解的交联剂。
