The polymerization of propylene using a mixture of racemic metallocenes and Ziegler-Natta catalysts was investigated. The polypropylene was obtained as a mixture of a fine powder and beads, with the powder being absorbed partially on the beads. The relative amount of the powder can be controlled by
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
