Abstract
Method of preparing a supported Ziegler-catalyst active in the polymerization of alpha-olefins to polymers particularly suited to working by blow-moulding, by reacting: (A) an organometallic compound of aluminium, and (B) the product of the reaction of titanium and vanadium halides with a solid support obtained by the spray drying of magnesium chloride in a mixed solution of ethanol and methanol, the support containing both ethanolic and methanolic alcoholic hydroxyl groups.
