Reaction Conditions

Reaction Steps

427.5 parts of 1-methoxy-2-propanol 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 18.5 parts of methacrylic acid, 46.5 parts of allyl methacrylate, 29.9 parts of benzyl acrylate (composition ratio of these methacrylic acid and esters was 28:48:24 in molar ratio), and 3.82 parts of V-65 (2,2′-azobis-(2,4′-dimethylvaleronitrile), manufactured by Wako Pure Chemical Co.) were dissolved in 427.5 parts of 1-methoxy-2-propanol 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. The obtained reaction liquid was poured into 5000 parts of water, and the resulting solid was separated by filtration and dried under vacuum to obtain a methacrylic acid/allyl methacrylate/benzyl acrylate terpolymer (terpolymer 3). The weight-average molecular weight of the terpolymer was 36,000 (converted as polystyrene).
