Patent ID: 7906599

Claim:
A transition metal compound (A) represented by the following general formula: wherein, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each independently are a hydrogen atom, a hydrocarbon group, a silicon-containing hydrocarbon group or a halogenated hydrocarbon group; however, any two of R 1 , R 2 , R 3 and R 4 are a substituent other than a hydrogen atom and any two of R 1 , R 2 , R 3 and R 4 are a hydrogen atom; further, adjacent R 1 , R 2 , R 3 and R 4 do not form a ring with each other; R 7 is a hydrocarbon group, a halogenated hydrocarbon group or a silicon-containing hydrocarbon group each having 6 or more carbon atoms; R 8 , R 9 , R 10 and R 11 each independently are a hydrogen atom, a hydrocarbon group, a silicon-containing hydrocarbon group or a halogenated hydrocarbon group; Q is a substituted silylene group or a substituted germylene group; X and Y each independently are a ligand that forms a σ-bond with M; and M is a transition metal of the group 4 of the periodic table.
