Abstract:
A transition metal catalyst compound represented by the general formula (III): ##STR20##wherein R.sup.1, R.sup.2, R.sup.4 and R.sup.5 are independently a hydrogen atom, a hydrocarbon group having 1 to 10 carbon atoms, a silicon-containing hydrocarbon group having 1 to 18 carbon atoms or a halogenated hydrocarbon group having 1 to 18 carbon atoms;Q is a bridging group of the two 5-membered rings, and is a divalent hydrocarbon group having 1 to 20 carbon atoms, a divalent halogenated hydrocarbon group having 1 to 20 carbon atoms, a silylene or an oligosilylene group which may have a hydrocarbon group or halogenated hydrocarbon group having 1 to 20 carbon atoms or a germylene group which may have a hydrocarbon group or halogenated hydrocarbon group having 1 to 20 carbon atoms;X and Y are indepndently a hydrogen atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms, a silicon-containing hydrocarbon group having 1 to 20 carbon atoms, a halogenated hydrocarbon group having 1 to 20 carbon atoms, an oxygen-containing hydrocarbon group having 1 to 20 carbon atoms, an amino group or a nitrogen-containing hydrocarbon group having 1 to 20 carbon atoms;M is a transition metal selected from the group consisting of elements belonging to Group 4-6 of the Periodic Table;wherein R.sup.9, R.sup.10, R.sup.11, R.sup.12, R.sup.13, R.sup.14, R.sup.15 and R.sup.16 are each independently a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms or a halogenated hydrocarbon group having 1 to 20 carbon atoms; andAr is an aryl group which may be substituted,provided that at least one of the two 7-membered rings is bonded to a halogenated hydrocarbon group having 1 to 20 carbon atoms.
