This invention has the objective of providing polymers having high oxygen permeability and high hydrophobicity and ophthalmic lenses comprising said polymers, and, as a result, provides novel monomers represented by general formula (a) below:
1
wherein, in formula (a), A
1
to A
9
indicate groups selected from the group consisting of H, alkyl groups, aralkyl groups, aryl groups and alkyl groups having 1 to 9 carbon atoms substituted with at least one group selected from epoxy groups, hydroxyl groups and amino groups, with at least one of A
1
to A
9
indicating said alkyl group of 1 to 9 carbon atoms substituted with at least one group selected from epoxy groups, hydroxyl groups and amino groups; a, b and c indicate 0 or 1; X indicates a polymerizable group having a carbon-carbon unsaturated bond; Z indicates groups selected from N—Y, O and S; Y indicates H, an alkyl group or an aryl group; and L indicates a divalent group having 1 to 10 carbon atoms.
该发明旨在提供具有高氧气渗透性和高疏水性的聚合物以及包括该聚合物的眼科透镜,因此提供了以下通式(a)所代表的新型单体:
其中,在式(a)中,A1到A9表示从H、烷基、芳基烷基、芳基和烷基中选择的基团,该烷基具有1到9个碳原子,被至少一个从环氧基团、羟基团和氨基团中选择的基团取代,其中至少一个A1到A9表示被至少一个从环氧基团、羟基团和氨基团中选择的基团取代的该烷基;a、b和c表示0或1;X表示具有碳-碳不饱和键的可聚合基团;Z表示从N-Y、O和S中选择的基团;Y表示H、烷基或芳基;L表示具有1到10个碳原子的二价基团。
