Procedure

36 g of styrene (ST), 4 g of N-phenylmaleimide (PM), 100 mg of azobisisobutyronitrile, and 50 ml of toluene were mixed, and a polymerization reaction was performed under a nitrogen atmosphere at 85° C. for 6 hours. After cooling, purification was performed by reprecipitation using chloroform-hexane. Thus, 25.6 g of an ST-PM (90:10) random copolymer (Mn=43000) was obtained.
