Title: Metallocene compounds, processes for the preparation thereof, catalyst components for olefin polymerization, and processes for the production of olefin polymers

Abstract: A metallocene compound is provided wherein to a transition metal compound is bonded a multidentate compound wherein a substituted cycloalkadienyl ring CA.sup.1 having therein a heteroaromatic group Ra containing an oxygen, sulfur or nitrogen atom on a cycloalkadienyl ring, preferably the five-membered ring thereof, and an unsubstituted or substituted cycloalkadienyl group CA.sup.2 or --(R.sup.1)N--, --O--, --S-- or --(R.sup.1)P--, preferably CA.sup.2, more preferably a substituted cycloalkadienyl group identical with CA.sup.1 are bonded through a divalent linking group. The metallocene compound is suitable as a principal ingredient of a catalyst for the polymerization of olefins, particularly achieving a very high effect in making the molecular weight of a polypropylene higher.
