Hydrocarbon-soluble magnesium-aluminum compositions

摘要

A composition of matter is disclosed comprising a dialkylmagnesium compound of the formula RMgR' in which R and R' are straight-chain alkyl groups of 1 to 4 carbon atoms each, either identical in length or differing by one carbon atom, and an aluminum diene polymer. The composition is soluble in aliphatic, cycloaliphatic, and aromatic hyrocarbon solvents.
