| titleOfInvention | Graft copolymer, solution containing the graft copolymer, and method of treating contact lens with the solution |
| abstract | A graft copolymer produced by polymerizing 2-hydroxyethyl methacrylate, or monomer mixture containing the monomer, by using initiator produced by copolymerizing (A) N-vinyllactam or styrene and (B) peroxy-fumarate or combination of the peroxy-fumarate and diester of fumaric acid, the peroxy-fumarate being represented by the formula (I):n n wherein R1 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 18 carbon atoms, or an aromatic hydrocarbon group containing 6 to 18 carbon atoms; and R2 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 13 carbon atoms, or a phenyl group. nA solution for treating a contact lens, including the above graft copolymer and a solvent dissolving the copolymer. A method of treating a contact lens, comprising the step of wetting a surface of the contact lens with the above solution, and the step of contacting the wetted surface with a poor solvent, thereby modifying the hydrophobic contact lens surface into a hydrophilic surface. |
