실험 절차

88 g of methyl ethyl ketone was placed in a 1000-mL three-necked flask equipped with a stirrer and a cooling tube, and heated to 72° C. in a nitrogen atmosphere. Into the flask, A solution prepared by dissolving 0.85 g of dimethyl 2,2′-azobisisobutyrate, 50 g of phenoxyethyl methacrylate, 13 g of methacrylic acid, and 37 g of methyl methacrylate in 50 g of methyl ethyl ketone was added dropwise to the flask over a period of 3 hours. After completion of the addition, the reaction was continued for further one hour, and then a solution prepared by dissolving 0.42 g of dimethyl 2,2′-azobisisobutyrate in 2 g of methyl ethyl ketone was added into the flask, and the solution was heated at 78° C. for 4 hours. The reaction solution thus obtained was reprecipitated twice in an excess amount of hexane, and the precipitated resin was dried to obtain 96.5 g of a phenoxyethyl methacrylate/methyl methacrylate/methacrylic acid (copolymerization ratio [% by mass]=50/37/13) copolymer (resin dispersant P-1).
