Transition metal catalyst component for polymerization, and method for producing a polymer by means thereof

A transition metal catalyst component for polymerization, represented by the following formula (1):

• 13
• in the formula, A is an unsubstituted or substituted benzindenyl group which can be represented by the following formula (5), (6) or (7):
• 14
• in the above formulae (5) to (7), each of R1a, R1b, R2a, R2b, R3a and R3b which are independent of each other, is hydrogen, a C1-20 alkyl group, a C6-10 aryl group or a C7-20 alkylaryl group, they may contain from one to three halogen atoms, silicon atoms, phosphorus atoms, oxygen atoms, boron atoms, nitrogen atoms, sulfur atoms and/or selenium atoms, they may have a structure of an OSiR3 group, a SiR3 group, an NR2 group, an OH group, an OR group or a PR2 group (each R represents a C1-10 hydrocarbon group), such a plurality of R1a, a plurality of R1b, a plurality of R2a, a plurality of R2b, a plurality of R3a or a plurality of R3b, may be the same or different from one another, and adjacent such substituents may together form a single or plural 5- to 8-membered aromatic or aliphatic rings;
• B is the same unsubstituted or substituted benzindenyl group as described above, or an unsubstituted or substituted cyclopentadienyl group, an unsubstituted or substituted indenyl group, or an unsubstituted or substituted fluorenyl group, which can be represented by the following formula (8), (9) or (10):
• 15
• in the above formulae (8) to (10), each of R4a, R4b, R5 and R6 which are independent of each other, is hydrogen, a C1-20 alkyl group, a C1-10 aryl group or a C7-20 alkylaryl group, they may contain from one to three halogen atoms, silicon atoms, phosphorus atoms, oxygen atoms, boron atoms, nitrogen atoms, sulfur atoms and/or selenium atoms, they may have a structure of an OSiR3 group, a SiR3 group, an NR2 group, an OH group, an OR group or a PR2 group (each R represents a C1-10 hydrocarbon group), and such a plurality of R4a, a plurality of R4b, a plurality of R5 or a plurality of R6, may be the same or different from one another;
• when both A and B are unsubstituted or substituted benzindenyl groups, both may be the same or different;
• Y is a substituted boron group having bonds to A and B and having hydrogen or a C1-20 hydrocarbon group, as a substituent, and the substituent in Y may contain from one to three nitrogen, boron, silicon, phosphorus, selenium, oxygen or sulfur atoms or may have a cyclic structure;
• X is each independently hydrogen, halogen, a C1-15 alkyl group, a C3-15 alkenyl group, a C6-10 aryl group, a C6-12 alkylaryl group, a silyl group having a C1-4 hydrocarbon substituent, a C1-10 alkoxy group, or an amide or amino group having a C1-22 hydrocarbon substituent, n is an integer of 0, 1 or 2, and when X is plural, the plurality of X may have bonds;
• and
• M is zirconium, hafnium or titanium.
