ABSTRACT This invention concerns solid organometallic hydrocarbyloxy magnesium halides of the formula ROMgX wherein RO is a hydrocarbyloxy group of 1 to 20 carbon atoms and X is halide, and a two step process for making these halides comprising: (a) reacting an activated magnesium metal with an alkyl halide of the formula R'X, in which R' is com- pound containing 1 to 20 carbon atoms, in a dry inert hydrocarbon media, under a dry inert atmosphere to produce a compound of the formula R'MgX in which R' and X have the meanings ascribed to them herein; and, (b) and reacting the R'MgX compound with an oxy- gen containing compound, containing 1 to 20 carbon atoms, selected from the group consisting of alcohols, ketones, aldehydes and esters to produce the compound ROMgX. When the oxygen containing compound is 2-alkyl substituted, the products are hydrocarbon soluble. The hydrocarbyloxy magnesium halides are useful in making supports for the supported type Ziegler-Natta (Z/N) olefin polymerization catalyst used in the pro- duction of polyolefins.
