    摘要: A lanthanide base olefin polymerization catalyst and its use in polymerization are disclosed. The lanthanide based catalyst is prepared by contacting a lanthanide halide with an ether, then contacting the resulting lanthanide composition with an alkali or alkaline earth metal alkyl compound, and depositing the resulting lanthanide product on a particulate support.
