Procedure

To 150 g of isopropanol were added 55 g of ethyl acrylate, 35 g of methyl methacrylate and 10 g of methacrylic acid. To the resulting mixture was added 0.5 g of benzoyl peroxide, and thereafter, the mixture thus-obtained was subjected to polymerization reaction at 80° C. for 7 hours. Subsequently, 200 g of water and 4 g of 28% ammonia water were added thereto, and then, the isopropanol was completely removed by distillation to obtain an ethyl acrylate/methyl methacrylate copolymer.
