Abstract

Method of preparing copolymers, characterized in that it comprises copolymerizing in bulk (placing the copolymerization mixture in a casting cell and heating the copolymerization mixture in said casting cell at 40-65º c) of 75% to 92% of methyl methacrylate and from 25% to 8% acrylic acid, removing the copolymer from said casting cell and neutralizing the acid groups of the acrylic acid by treating at least one surface of said copolymer with a basic solution having a concentration of 0.1% at 5% for a time of up to 48 hours, to obtain a copolymer with hydrophilic surface.
