The chemical interaction between the procatalyst MgCl 2 /TiCl 4 /EB (EB = ethylbenzoate) and the cocatalyst triethylaluminium was investigated with the purpose to find a relationship between the degree of titanium reduction and the catalytic activity in ethene and propene polymerizations. This inter
Propylene polymerization was investigated with the TiC14/MgCI 4 supported catalyst with the stereoregulating donor pair dibutylphtalate (DBPH)/triethoxyphenylsilane (TEPS) in heptane with A1Et 3 as cocatalyst in the presence of hydrogen. It was shown that there is an activation effect by the influen
