## 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
## Abstract In propylene polymerization with MgCl~2~βsupported ZieglerβNatta catalysts, it is known that the reduction of TiCl~4~ with alkylaluminum generates Ti^3+^ active species, and at the same time, leads to the growth of TiCl~__x__~ aggregates. In this study, the aggregation states of the Ti
## Abstract Experiments designed to prepare ZieglerβNatta catalysts with controlled particle morphology are reported. Different dealcoholation processes are used on the adduct MgCl~2~βΒ·β__n__EtOH to prepare the catalysts: either thermal treatment or chemical dealcoholation employing different subst
