## Abstract The activity of Ti(OEt)~4~ (Et: C~2~H~5~) in combination with methylaluminoxane (MAO) in the syndiospecific polymerization of styrene was investigated concenrning the dependence on temperature, mole ratio of Al/Ti, concentrations of monomer, catalyst and MAO. Reaction products of Ti(OEt
There is further consideration of the model of the active site of polymerization on heterogeneous Ziegler-Natta catalysts. It is located on basal planes of lattice crystals of type a-TiCl3 or VCI3 and has two vacancies at the transition metal atom. One of these vacancies is blocked by the helical po
