[0196]In an autoclave, toluene (3.7 ml) was placed under a nitrogen atmosphere. The interior temperature was increased to 70° C., and ethylene was pressurized to 0.60 MPa to stabilize the system. Then, a toluene solution (400 μL) of methylaluminoxane (TMAO, manufactured by Tosoh Finechem Corp.) having a concentration of 0.25 mmol / mL was supplied to the autoclave. Then, a toluene solution (900 μL) of 0.01 μmol of [1-(1-methyl-1-phenylsilyl)-cyclopentadienyl]titanium trichloride (complex 1) and 0.09 μmol of dimethylsilylene(tetramethylcyclopentadienyl)(3-tert-butyl-5-methyl-2-phenoxy)titanium dichloride (complex 2) was supplied to the autoclave to initiate the polymerization. The polymerization was performed at 70° C. for 3 minutes. During the polymerization, ethylene gas was supplied so as to maintain the whole pressure of the autoclave at a constant value. After the completion of the polymerization, the ethylene in the autoclave was purged and the volatile component therein was remo...

Then, a toluene solution (400 μL) of methylaluminoxane (TMAO manufactured by Tosoh Finechem Corp.) having a concentration of 0.25 mmol / mL was supplied to in the autoclave. Then, 900 μL of a toluene solution containing 0.005 μmol of [1-(1-methyl-1-(3,5-dimethylphenyl)ethyl)-3-trimethylsilylcyclopentadienyl]titanium trichloride (complex 3) and 0.095 μmol of dimethylsilylene(tetramethylcyclopentadienyl)(3-tert-butyl-5-methyl-2-phenoxy)titanium dichloride (complex 2) was supplied to the autoclave to initiate the polymerization, which was performed at 70° C. for 3 minutes. During the polymerization, ethylene gas was supplied so as to maintain the whole pressure of the autoclave at a constant value.

During the polymerization, ethylene gas was supplied so as to maintain the whole pressure of the autoclave at a constant value. After the completion of the polymerization, the ethylene within the autoclave was purged and the vola...
