Procedure

First, 100 g of styrene, 0.33 g of methacrylic acid, and 0.5 g of BPO (benzoyl peroxide) were dissolved in benzene (solvent), and the resulting solution was kept at 80° C. for 3 hours. Then, benzene as solvent was removed, and the styrene-methacrylic acid copolymer was obtained. This copolymer is hereinafter referred to as SMCPb. The content of methacrylic acid as a functional monomer in SMCPb was 0.5 mol %.
