ABSTRACT:
A process for producing an improved titanium catalyst for use in the polymerization of olefins comprising heating a magnesium dialkoxide and an alcohol adduct of a magnesium dihalide to form a solid product, treating said solid product with an alcohol to form an alcohol treated solid product, and then reacting said alcohol treated solid product with a halogen-containing titanium compound. The reaction product of said alcohol treated solid product with the halogen-containing titanium compound may optionally be reacted with an organoaluminum compound. The products of the processes described in the preceding two sentences is an improved titanium catalyst which is generally used with an organoaluminum olefin polymerization cocatalyst.
