    摘要: Metallocycle metallocenes are produced by reacting a first metallocene having an aralkyl group or an aryl dialkyl silyl group attached to a cyclodienyl group with about two molar equivalents of an alkali metal alkyl having at least 4 carbon atoms. The use of the metallocycle metallocenes as components of catalyst for the polymerization of olefins is also disclosed.
