ABSTRACT:
A component of a polymerization catalyst is prepared by reacting an organo-magnesium halide with a solid, inorganic oxide, then reacting the product with a Lewis Base compound, particularly an ester and finally with titanium tetrachloride. After reacting the organo-magnesium halide with the inorganic oxide it may be treated with a halogenating agent before it is reacted with the Lewis Base compound. The product obtained is combined with an organo-aluminium compound preferably together with a Lewis Base and used to polymerize an olefine monomer. The catalyst has a high activity, is stereospecific and has a lower proportion of halogen than some other catalyst systems.
