[0082]To a stainless steel autoclave (capacity: 5 L) purged with nitrogen, 1-decene (2.5 L), which had been degassed and dehydrate through nitrogen bubbling in advance, was fed. The temperature of the autoclave was elevated to 105° C., and a 1.0-mol / L triisobutylaluminum / toluene solution (6.3 mL) and a 10-mmol / L N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate / toluene suspension (5 mL) were added to the autoclave.
[0083]Subsequently, a 10-mmol / L (1,1′-dimethylsilylene)(2,2′-dimethylsilylene)-bis(cyclopentadienyl)zirconium dichloride / toluene solution (2.5 mL) was added to the autoclave, and the contents were allowed to react at 105° C. for 6 hours, while hydrogen (50 kPa) was continuously added thereto.
[0084]In the above reaction, the ratio of metallocene compound to 1-decene was 0.025 mmol / L(1-decene); the ratio by mole of triisobutylaluminum / metallocene compound was 100; and the ratio by mole of borate compound / metallocene compound was 2. The reaction was terminated with 1% d...

[0086]A stainless steel autoclave (capacity: 2 L) was sufficiently dried and purged with nitrogen. Under nitrogen, 1-dodecene (780 mL) and 1-octene (420 mL) were added to the autoclave, and the temperature thereof was elevated to 105° C. Subsequently, under nitrogen, triisobutylaluminum (0.3 mmol) (1 mmol / mL toluene solution; 0.3 mL), (1,1′-dimethylsilylene)(2,2′-dimethylsilylene)-bis(cyclopentadienyl)zirconium dichloride (15 μmol) (5 μmol / mL toluene solution; 3 mL), and N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate (60 μmol) (20 μmol / mL slurry in toluene; 3 mL) were added to the autoclave, and the mixture was stirred for a while. Then, hydrogen (0.05 MPaG) was fed thereto, and polymerization was initiated. The polymerization reaction was performed at 105° C. for 120 minutes, and the polymerization was terminated through addition of methanol (10 mL) to the polymerization system. The contents were removed from the autoclave and added to 1 mass % aqueous NaOH (500 mL) with s...
