摘要:
A silicone-containing polymer material containing an internal wetting agent and being excellent in transparency, the silicone-containing polymer material being improved in antifouling property against lipids. The polymer material of the present invention is a polymer material, which is obtained by polymerizing a polymerizable mixture containing monomer components (a) and a hydrophilic polymer component (b), wherein the monomer components (a) include a silicone-containing monomer (a-1) having a siloxane bond and being free of any hydroxyl group, and a compatibilizing monomer (a-2) having a hydrogen bonding proton-containing group and being free of any silicon atom, and wherein the compatibilizing monomer has four or more carbon atoms, excluding carbon atoms contained in a polymerizable functional group, and has a solubility of less than 0.03 g/mL in water at 25° C.
