Procedure

A reaction vessel equipped with a condenser, a stirrer, and a nitrogen inlet pipe was charged with 300 parts of ethyl acetate, 300 parts of a mixture of styrene and acrylic monomers (styrene/2-ethylhexyl acrylate/acrylic acid/2-hydroxyethyl acrylate=75/15/5/5), and 10 parts of azobis isobutylnitrile. The mixture was subjected to a reaction for 15 hours at 60° C. in nitrogen atmosphere under normal pressures. After adding 200 parts of methanol, the mixture was further agitated for 1 hour, supernatant liquid was removed, and dried under reduced pressures. Thus, a styrene-acrylic copolymer resin was prepared.
