Conditions

Temperature: 90 °C

Procedure

40 parts by weight of methyl isobutyl ketone were put into a flask with a stirrer, and heated to 90° C. with stirring in a stream of nitrogen gas. A mixture of 95 parts by weight of styrene, 10 parts by weight of butyl acrylate and 25 parts by weight of benzoyl peroxide was added dropwise over a period of 6 hours to the methyl isobutyl ketone which was maintained at 90° C. Subsequently, the above-mentioned mixture was subjected to polymerization at 90° C. for 10 hours, whereby a styrene-butyl acrylate copolymer solution was obtained.
