<p>A transition metal compound of the following formula (1) as catalyst component for the production of an aromatic vinyl compound polymer or an aromatic vinyl compound-olefin copolymer: <CHEM> wherein A is an unsubstituted or substituted benzindenyl group of the following formula K-2, K-3 or K-4: <CHEM> wherein each of R1 to R3 is hydrogen, a C1-20 alkyl group, a C6-10 aryl group, a C7-20 alkylaryl group, a halogen atom, OSiR3, SiR3 or PR2 (wherein each R is a C1-10 hydrocarbon group), provided that the plurality of R1, the plurality of R2 and the plurality of R3 may be the same or different, respectively, and each pair of adjacent R1, adjacent R2 and adjacent R3 may together, with the atoms joining them, form a 5- to 8- member aromatic or aliphatic ring, B is an unsubstituted or substituted benzindenyl group of the same chemical formula as A, or an unsubstituted or substituted cyclopentadienyl group, an unsubstituted or substituted indenyl group or an unsubstituted or substituted fluorenyl group, of the following formula K-5, K-6 or K-7: <CHEM> wherein each of R4 to R6 is hydrogen, a C1-20 alkyl group, a C6-10 aryl group, a C7-20 alkylaryl group, a halogen atom, OSiR3, SiR3 or PR2 (wherein each R is a C1-10 hydrocarbon group), provided that the plurality of R4, the plurality of R5 and the plurality of R6 may be the same or different, respectively, when both A and B are unsubstituted or substituted benzindenyl groups, they may be the same or different, Y is a methylene group or a silylene group, which has bonds to A and B and which has, as substituents, hydrogen or a C1-15 hydrocarbon group, wherein the substituents may be the same or different from each other, or Y may have, together with the substituents, a cyclic structure, X is hydrogen, a halogen atom, an alkyl group, an aryl group, an alkylaryl group, a silyl group, a methoxy group, an ethoxy group, an alkoxy group or a dialkylamide group, and M is zirconium, hafnium or titanium.</p> |
