Olefin polymerization catalyst and method for production and use

摘要

A new highly active olefin polymerization catalyst as disclosed. The catalyst is prepared by contacting a magnesium dihalide with a halogenated titanium alkoxide to obtain a first solid, washing this first solid until it is substantially free of soluble halogenated titanium alkoxide, then contacting the first solid with a titanium tetrachloride to yield a second solid.
