A soluble ethylene catalyst were obtained by mixing a methylene dichloride solution of dichlorobislT-cyclopentadienyl) titanium (Cp2TiCI2) with a heptane solution of ethylaluminium sesquichloride (AlzEt3C13) or of diethylaluminium chloride {AIEt2CI). Ethylene was polymerized using these catalysts; t
Comparison with the conventional ZieglereNatta catalyst TiCl 4 /MgCl 2 (I), the modified supported Zie-glereNatta catalysts (iso-PentylO)TiCl 3 /MgCl 2 (II) and (BzO)TiCl 3 /MgCl 2 (III) were prepared as efficient catalysts for copolymerization of ethylene with 1-octene. The complexes (II) and (III)
