Procedure

180 parts of 1-methoxy-2-acetoxy propane were charged in a reaction vessel and heated under a nitrogen flow so that the internal temperature of the vessel was 70° C. Then a solution in which 17.1 parts of methacrylic acid, 42.9 parts of allyl methacrylate, 30.0 parts of benzyl methacrylate (composition ratio of these methacrylic acid and esters thereof was 28:48:24 in molar ratio), 2.87 parts of dodecylmercaptane and 3.52 parts of V-65 (2,2′-azobis-(2,4′-dimethylvaleronitrile), manufactured by Wako Pure Chemical Co.) were dissolved in 180 parts of 1-methoxy-2-acetoxypropane was dropwise added into the vessel over a period of 2.5 hours. The mixture was agitated further for 2 hours under heating at 70° C. to obtain a methacrylic acid/allyl methacrylate/benzyl methacrylate terpolymer (terpolymer 1). The weight-average molecular weight of the terpolymer was 33,000 (converted as polystyrene).
