실험 절차

In a 0.5-liter reactor equipped with a stirrer were placed 100 ml of styrene and 10.0 mmol as aluminum atom of methylaluminoxane obtained in the above Example 1 (1), and the resultant was stirred at the polymerization temperature of 40° C. for 30 minutes. Subsequently, 0.05 mmol as titanium atom of pentamethylcyclopentadienyltitanium trimethoxide was added, followed by 100 ml of methyl methacrylate. Then, polymerization was carried out at 70° C. for 4 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-methyl methacrylate copolymer was 4.3 g. Intrinsic viscosity measured in 1,2,4-trichlorobenzene at 135° C. was 0.48 dl/g.
