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
The profiles of X-ray diffraction patterns have been examined for several powder samples of di-TiCla, obtained by mechanical activation of 3,-TIC13 and presenting different catalytic activities in the Ziegler-Natta stereospecific polymerization of propylene to isotactic polypropylene. Particular att
