ABSTRACT:
A titanium catalyst for polymerization of olefins is prepared by reduction of TiCl.sub.4 with a mixture of AlEt.sub.2 Cl and AlEt.sub.3, where at high AlEt.sub.3 to AlEt.sub.2 Cl ratios the aluminum reducing agents are added to the TiCl.sub.4 solution. The reduction is performed from -50.degree. to 0.degree. C in a hydrocarbon and the reduced titanium compound is activated by heating to a higher temperature and subsequently is used with a cocatalyst for polymerization of olefins.
