## Abstract Polymerization of propene at β78Β°C in the presence of a homogeneous catalytic system based on a Ni(II) diimine derivative and methylaluminoxane affords prevailingly syndiotactic crystalline poly(propylene) (rr triad content β80%). ^13^C NMR analysis of the polymer microstructure indicat
## Abstract Several types of SiO~2~βsupported metallocene catalysts were prepared using chemically modified silica gel. Polymerization of propene was conducted with these catalysts combined with methylaluminoxane (MAO) or ordinary alkylaluminiums. Highly isotactic poly(propylene) with high molecula
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
