ABSTRACT:
Stable liquid hydrocarbon-soluble novel magnesium dialkoxide compositions useful as or in the preparation of polymerization catalysts and initiators for the polymerization of alpha-olefins and diolefins are prepared, for instance, by reacting certain organomagnesium compounds in liquid hydrocarbon solvents with (a) aliphatic, cycloaliphatic or acyclic beta- and gamma-alkyl-substituted C.sub.5 -C.sub.18 monohydric secondary and tertiary alcohols; or (b) mixtures of (a) with beta- and/or gamma-alkyl-unsubstituted C.sub.3 -C.sub.18 aliphatic secondary or tertiary alcohols; or (c) mixtures of (a) with C.sub.1 -C.sub.18 aliphatic primary linear alcohols. Such dialkoxides, and complexes thereof, soluble in hydrocarbon or chlorinated hydrocarbon solvents, can be reacted with triorganoaluminum compounds such as, for instance, TIBAL, organolithium, or organopotassium compounds, e.g., alkyllithiums, or alkali metal alkoxides. An illustrative example of the novel magnesium dialkoxides is magnesium bis-2,3-dimethyl-3-pentyloxide.
