Ethylene → Ethylene styrene

340 mL of dehydrated toluene, 50 mL of styrene and TIBA (1.8 mmol) were placed in a 1 L autoclave, which had been dried by heating, at room temperature under a nitrogen atmosphere. After making the temperature thereof to 70° C. under stirring, mL of a toluene solution of (9-ethyl-1,2,3,4-tetrahydro-1-fluorenyl)-bis(N,N-dimethylaminobenzyl)scandium obtained in the item (E) of Example 1 (0.027 mmol) and triphenylcarbenium tetrakispentafluorophenylborate (0.027 mmol), which had been mixed in advance, was added thereto. The mixture was homopolymerized for styrene for 5 minutes, and then further polymerized for 5 minutes while maintaining the pressure to 0.1 MPa with ethylene. After completing the polymerization reaction, the reaction product was placed in a methanol-hydrochloric acid solution, and after stirring sufficiently, the polymer was filtered off, sufficiently rinsed with methanol, and dried to provide 43 g of a styrene-ethylene copolymer.
