The polymerization of Example 1 was repeated except that in place of the benzene-soluble organoaluminum oxy-compound, the benzene-insoluble organoaluminum oxy-compound as prepared above was used in an amount of 0.1 mg atom in terms of Al atom, 1 mmol of triisobutylaluminum was further used, the amount of the titanium catalyst component used was changed to 1×10-3 mg atom and the amount of the zirconium component used was changed to 3×10-4 mg atom, whereby 49.0 g of an ethylene/4-methyl-1-pentene copolymer having MFR of 0.05 g/10 min, a density of 0.904 g/cm3, an amount of decane-soluble portion at 23° C. of 0.12% by weight and Mw/Mn of 7.0 was obtained.
