Abstract

Procedure for obtaining a catalyst for the polymerization of olefins comprising chromium oxides of titanium and silicon, with a minor amount of chromium being hexavalent, characterized by the steps of adding an aqueous solution of an alkali metal silicate to an aqueous solution acid containing a titanium compound thereby causing a titanium-containing silica hydrogel to precipitate, which is recovered and dried.
