Reaction Conditions

Reaction Steps

803 parts of 1-methoxy-2-acetoxypropane 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 54.0 parts of methacrylic acid, 135.6 parts of allyl methacrylate, 90.4 parts of cyclohexyl methacrylate (composition ratio of these methacrylic acid and esters thereof was 28:48:24 in molar ratio), 4.53 parts of dodecylmercaptane and 11.1 parts of V-65 (2,2′-azobis-(2,4′-dimethylvaleronitrile), manufactured by Wako Pure Chemical Co.) were dissolved in 803 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/cyclohexyl methacrylate terpolymer (terpolymer 2). The weight-average molecular weight of the terpolymer was 36,000 (converted as polystyrene).
