Abstract:
A transition metal compound represented by the following general formula (I): ##STR10##wherein R.sup.1, R.sup.2, R.sup.4 and R.sup.5 each independently represent a hydrogen atom, a C.sub.1-10 hydrocarbon group, a C.sub.1-18 silicon-containing hydrocarbon group or a C.sub.1-18 halogenated hydrocarbon group; R.sup.3 and R.sup.6 each independently represent a C.sub.3-10 saturated or unsaturated divalent hydrocarbon group, with the proviso that at least one of R.sup.3 and R.sup.6 has from 5 to 8 carbon atoms; R.sup.7 and R.sup.8 each independently represent a C.sub.1-20 hydrocarbon group, a C.sub.7-30 oxygen-containing aryl group, a C.sub.7-30 nitrogen-containing aryl group or a C.sub.7-30 sulfur-containing aryl group, with the proviso that at least one of R.sup.7 and R.sup.8 is a C.sub.7-30 oxygen-containing aryl group, a C.sub.7-30 nitrogen-containing aryl group or a C.sub.7-30 sulfur-containing aryl group; m and n each independently represent an integer of from 0 to 20, with the proviso that m and n are not 0 at the same time and if m or n is an integer of not less than 2, R.sup.7 's or R.sup.8 's may be connected to each other in arbitrary positions to form a new cyclic structure; Q represents a divalent C.sub.1-20 hydrocarbon group, a divalent C.sub.1-20 halogenated hydrocarbon group or a silylene, oligosilylene or germylene group which may have a C.sub.1-20 hydrocarbon or halogenated hydrocarbon group; X and Y each independently represent a hydrogen atom, a halogen atom, a C.sub.1-20 hydrocarbon group, a C.sub.1-20 silicon-containing hydrocarbon group, a C.sub.1-20 halogenated hydrocarbon group, a C.sub.1-20 oxygen-containing hydrocarbon group, an amino group or a C.sub.1-20 nitrogen-containing hydrocarbon group; and M represents a transition metal element belonging to the groups 4 to 6 in the periodic table.
