Procedure

140 g of benzyl methacrylate, 17 g of methacrylic acid, 200 g of ethanol and 1.5 g of azoisobutyronitrile were mixed and heated by an oil bath and reacted under reflux for 8 hours in a nitrogen atmosphere. This reaction solution was reprecipitated in pure water to obtain a benzyl methacrylate/methacrylic acid copolymer resin. Neutralizing titration was carried out with KOH, whereby the acid value of the resin was 70 mg.KOH/g. Further, the weight average molecular weight Mw was 40,000, the number average molecular weight Mn was 10,000 and the molecular weight distribution Mw/Mn was 4.
