Abstract:
A metallocene compound represented by the following formula (1) ##STR8## wherein CA.sup.1 represents a substituted cycloalkadienyl group selected from the group consisting of a substituted cyclopentadienyl group, a substituted indenyl group, a substituted tetrahydroindenyl group, a substituted benzoindenyl group and a substituted fluorenyl group; each Ra represents independently a heteroaromatic group selected from the group consisting of furyl, thienyl, pyridyl, benzofuryl, benzothienyl, quinolyl, pyrrolyl having a bond at positions other than the 1-position and indolyl having a bond at positions other than the 1-position; each R.sup.1 represents independently a halogen atom, a hydrocarbon group of 1-20 carbons, a halogenated hydrocarbon group wherein a part or all of the hydrogen atoms in the hydrocarbon group are substituted by a halogen atom, a silyl group substituted by said hydrocarbon group or said halogenated hydrocarbon group, an amino group substituted by said hydrocarbon group or a monocyclic or polycyclic amino group; p is an integer of 1-8; m is 0 or an integer of 1-8; Z represents a linking group selected from the group consisting of (CA.sup.2) (Ra).sub.q (R.sup.1).sub.n, --O--, --S--, --NR.sup.1 -- and --PR.sup.1 -- wherein CA.sup.2 represents an unsubstituted or substituted cycloalkadienyl group; Ra and R.sup.1 have the same meanings as defined above, Ra may be identical with or different from said Ra on CA.sup.1 and R.sup.1 may be identical with or different from said R.sup.1 on CA.sup.1 ; and q and n are each independently 0 or an integer of 1-8; Y represents a divalent linking group selected from the group consisting of --C(R.sup.2).sub.2 --, --C.sub.2 (R.sup.2).sub.4 --, --C.sub.6 (R.sup.2).sub.10 --, --C.sub.6 (R.sup.2).sub.4 --, --Si(R.sup.2).sub.2 --, --Ge(R.sup.2).sub.2 -- and --Sn(R.sup.2).sub.2 -- wherein each R.sup.2 represents independently a hydrogen atom, a halogen atom, a hydrocarbon group of 1-20 carbons, a halogenated hydrocarbon group wherein a part or all of the hydrogen atoms in the hydrocarbon group are substituted by a halogen atom or a silyl group substituted by said hydrocarbon group or said halogenated hydrocarbon group; M represents a transition metal atom selected from the group consisting of Ti, Zr and Hf; and each X.sup.1 represents independently a halogen atom, a hydrocarbon group of 1-20 carbons, a halogenated hydrocarbon group wherein a part or all of the hydrogen atoms in the hydrocarbon group are substituted by a halogen atom or a silyl group substituted by said hydrocarbon group or said halogenated hydrocarbon group provided that Ra is not pyridyl, quinolyl or furyl when present on the 6-member ring of the substituted indenyl group and that Ra is not pyridyl when CA.sup.1 is a substituted cyclopentadienyl group.
