Abstract
Compositions having the formula X.sub.n Mg(OR).sub.2-n in which X is chloro, bromo or iodo; R is a C.sub.1 -C.sub.10 alkyl group and n is a value from about 0.2 to about 1.9 are produced by a process comprising preparing an alkanol adduct of a magneisum halide, reacting the product of this step with metallic magnesium, and drying the product. The compositions are useful as olefin polymerization catalyst components and supports.

A process for the production of a halide- and alkoxy-containing magnesium composition having the formula
- X.sub.n Mg(OR).sub.2-n
- in which X is chloro, bromo, or iodo;
- R is a C.sub.1 -C.sub.10 alkyl group;
- and n is a value from about 0.2 to about 1.9 comprising:
- (a) preparing an adduct of a magnesium halide having the formula MgX.sub.2 with an alkanol having the formula ROH;
- (b) reacting the product of step (a) with metallic magnesium;
- and
- (c) drying the product of step (b) to obtain a halide- and alkoxy-containing magnesium composition.
