ABSTRACT:
High activity catalysts for the polymerization of ethylene and other .alpha.-olefins are made by contacting a soluble magnesium compound of the general formula Mg(OSiR.sup.1 R.sup.2 R.sup.3).sub.2, wherein each of R.sup.1, R.sup.2, and R.sup.3 is, independently, alkyl, alkoxy or aryl with a metal alkoxide, or a mixture of a titanium tetraalkoxide with an alkoxide of another transition metal, in a saturated aliphatic hydrocarbon solution, followed by chlorination and precipitation by a suitable chlorinating agent. These catalysts show high activity for the polymerization of ethylene, especially under slurry polymerization conditions.
