Abstract

Procedure for preparing an olefin polymerization catalyst by depositing chromium oxide on a support consisting essentially of silica precipitated in an aqueous solution of an alkali metal silicate, characterized in that the silicate is precipitated by adding the solution of alkali metal silicate to an aqueous solution of an ammonium salt and then separating and drying the precipitated silica gel.
