In a 0.5-liter reactor equipped with a stirrer were placed 100 ml of styrene and 6.0 mmol as aluminum atom of methylaluminoxane obtained in the above Example 1 (1), and the resultant was stirred at the polymerization temperature of 30° C. for 30 minutes. Subsequently, 0.03 mmol as titanium atom of pentamethylcyclopentadienyltitanium trimethoxide was added. At the same time, 100 g of N-phenylmaleimide was dissolved in 300 ml of toluene, and after sufficiently replaced with nitrogen, this solution was added and polymerization was carried out at 40° C. for 5 hours with stirring. After the reaction was over, methanol was poured to stop the reaction. Further, a mixture of methanolhydrochloric acid was added to decompose the catalyst components. Then, washing with methanol was repeated three times. The yield of thus obtained styrene-N-phenylmaleimide copolymer was 51.5 g. Intrinsic viscosity measured in 1,2,4-trichlorobenzene at 135° C. was 0.66 dl/g.
