## Abstract The thermodynamics of the reaction of an ethylene molecule with the Cp~2~TiCH~3~Cl/Al(CH~3~)~2~Cl system (Cp = η~5~‐C~5~H~5~), as a model for olefin polymerization with homogeneous Ziegler‐Natta catalysts, was investigated via quantum mechanical DFT calculations. The comparison of the c
Ethylene polymerization reactions with many Ziegler-Natta catalysts exhibit several features which differentiate them from polymerization reactions of ␣-olefins: a relatively low ethylene reactivity, higher polymerization rates in the presence of ␣-olefins, a high reaction order with respect to ethy
Grignard reagent PhMgCl was added during the preparation of the catalyst system MgCl 2 /di-n-butyl phthalate (DNBP)/TiCl 4 {AlEt 3 /diphenyl dimethoxyl silane (DPDMS) to improve its performance. It was found that PhMgCl could enhance both the activity of the catalyst and the isotacticity of the prod
