Abstract:
A catalyst component comprising a transition metal compound represented by the general formula (VI): wherein R1, R2, R4 and R5 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; R3 and R6 are independently a saturated or unsaturated divalent hydrocarbon group having 3 to 10 carbon atoms and forms a condensed ring in cooperation with 5-membered rings to which R3 and R6 are respectively bonded, with the proviso that at least one of R3 and R6 has 5 to 8 carbon atoms and forms a 7- to 10-membered condensed ring having at least one unsaturated bond derived from R3 or R6; R7 and R8 are independently a hydrocarbon group having 1 to 20 carbon atoms, an oxygen-containing hydrocarbon group having 1 to 20 carbon atoms, an amino group, a nitrogen-containing hydrocarbon group having 1 to 20 carbon atoms or a sulfur-containing hydrocarbon group having 1 to 20 carbon atoms; Q is a silicon atom, a germanium atom or a tin atom; A is a divalent unsaturated hydrocarbon group having 3 to 12 carbon atoms and forms a ring in cooperation with the Q to which A is bonded; Ra is a saturated or unsaturated hydrocarbon group having 1 to 10 carbon atom; m and n are independently an integer of 0 to 20 with the proviso that m and n are not 0 at the same time, that when m or n is an integer of not less than 2, the R7 or the R8 may be bonded to each other to form a ring; 1 is an integer of 0 to 22, when 1 is an integer of not less than 2, the Ra may be bonded to each other to form a ring; X and Y are independently 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; and M is a transition metal selected from the group consisting of elements belonging to Group 4-6 of the Periodic Table.
