Kinetics of ethylene homopolymerization reactions and ethylene/1-hexene copolymerization reactions using a supported Ziegler-Natta catalyst was carried out over a broad range of reaction conditions. The kinetic data were analyzed using a concept of multicenter catalysis with different centers that r
Ethylene polymerization reactions with many Ziegler-Natta catalysts exhibit several features which differentiate them from polymerization reactions of β£-olefins: a relatively low ethylene reactivity, higher polymerization rates in the presence of β£-olefins, a high reaction order with respect to ethy

## Abstract The thermodynamics of the reaction of an ethylene molecule with the Cp~2~TiCH~3~Cl/Al(CH~3~)~2~Cl system (Cp = Ξ·~5~βC~5~H~5~), as a model for olefin polymerization with homogeneous ZieglerβNatta catalysts, was investigated via quantum mechanical DFT calculations. The comparison of the c
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
