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

A~traet--Temperature dependences of the stereoregularity parameters of the most stereospecific active centres of =-TiCI3:AIEt 3 catalytic system from -25 to 120 and of VCI3--AIEt 3 catalytic system from -15: to 90 c have been measured. It was found that this temperature dependence could be represent
