Embodiment 1
[0223] Example 1 (reaction carried out by preactivation under 50°C and hydrogen pressure of 0.15MPa)
[0224] Into a 50 ml Schlenk bottle equipped with a stir bar, toluene (13 ml) and 1-decene (2 ml, 1.5 g) which had been well bubbled with nitrogen were added under a nitrogen stream. Then, triisobutylaluminum (0.4 mmol: 0.2 ml of a solution diluted to 2 mmol / liter with toluene), dimethylanilinium tetrakis(pentafluorophenyl) borate (60 μmol: after vacuum drying) were added in turn while stirring. Dissolve 3 mL of a solution of 20 μmol / ml in toluene), (1,1'-ethylene)(2,2'-dimethylsilylene)-bis(indenyl)zirconium dichloride (40 μmol: Dissolve 2 mL of 20 μmol / ml solution with heptane). By performing stirring for 6 hours, a solution-like preactivated catalyst (preactivated catalyst concentration: 2 μmol / ml) was obtained.
[0225] Into a heat-dried 1-liter autoclave, 400 ml of 1-decene, 1 mmol of triisobutylaluminum, and the above preactivated catalyst (1 ml, Zr: 2 μmol) were charg...
Embodiment 2（50
[0226] Example 2 (progressive reaction at 50°C and hydrogen pressure of 0.15MPa)
[0227] In a 1-liter autoclave that has been heated and dried, add 400 ml of 1-decene, 1 mmol of triisobutylaluminum, (1,1'-ethylene)(2,2'-dimethylmethylene Silyl)-bis(indenyl)zirconium dichloride 2 micromoles, dimethylanilinium tetrakis(pentafluorophenyl)borate 8 micromoles, and then introduce hydrogen 0.15MPa. After polymerization was carried out at a temperature of 50° C. for 5 hours while stirring, an α-olefin oligomer was obtained. After the obtained reaction solution was treated as described in Example 1, physical properties were measured.
Embodiment 3（90
[0228] Example 3 (progressive reaction at 90°C, hydrogen pressure 0.15MPa)
[0229] In a 1-liter autoclave that has been heated and dried, add 400 ml of 1-decene, 1 mmol of triisobutylaluminum, (1,1'-ethylene)(2,2'-dimethylmethylene Silyl)-bis(indenyl)zirconium dichloride 2 micromoles, dimethylanilinium tetrakis(pentafluorophenyl)borate 8 micromoles, and then introduce hydrogen 0.15MPa. After polymerization was carried out at a temperature of 90° C. for 5 hours while stirring, an α-olefin oligomer was obtained. After the obtained reaction solution was treated as described in Example 1, physical properties were measured.
