Procedure

The polymerization of Example 18 was repeated except that in place of the benzene-soluble organoaluminum oxy-compound, there were used 0.3 mg atom in terms of the aluminum atom of the benzene-insoluble organoaluminum oxy-compound as prepared above, 1 mmole of triisobutylaluminum and 1×10-3 mg atom in terms of titanium atom of the solid catalyst component, whereby 30.2 g of an ethylene/4-methyl-1-pentene copolymer having MFR of 0.81 g/10 min, a density of 0.917 g/cm3, an amount of decane soluble portion of 1.4% by weight and Mw/Mn of 6.1 was obtained.
