摘要

A metallocene compound is new. New metallocene compound is of formula (A). [Image] M : Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, or W; R 1>, R 2>H, 1-10C alkyl, 1-10C alkoxy, 6-10C aryl, 6-10C aryloxy, 2-10C alkenyl, 2-4C alkenyl, 7-40C arylalkyl, 7-40C alkylaryl, 8-40C arylalkenyl, OH, or halogen atom; or a conjugated diene (having up to 30 atoms not counting hydrogen) which is optionally substituted with hydrocarbyl(s), tri(hydrocarbyl)silyl groups, or tri(hydrocarbyl)silylhydrocarbyl; R, R 3>, R 4>H, halo, 1-10C alkyl which may be halogenated, 6-10C aryl which may be halogenated, 2-10C alkenyl, 7-40C arylalkyl, 7-40C alkylaryl, 8-40C arylalkenyl, -NR' 2, -SR', -OR', -OSiR' 3, or -PR' 2; R' : halo, 1-10C alkyl, or 6-10C aryl; R 1> 3>a compound of formula (B); R 1> 7>-R 2> 4>H, 1-10C alkyl, 1-10C alkoxy, 6-10C aryl, 6-10C aryloxy, 2-10C alkenyl, 2-4C alkenyl, 7-40C arylalkyl, 7-40C alkylaryl, 8-40C arylalkenyl, OH, or halogen atom; M 2>C, Si, Ge, Sn Two or more adjacent radicals R 1> 7>-R 2> 4> including R 2> 0> and R 2> 1> together with intervening atoms of the phenyl group(s) form ring(s) fused with the phenyl group(s). Two adjacent R radicals together with the atoms connecting them are joined to form a ring. Independent claims are also included for: (A) a catalyst composition comprising the reaction product of the inventive metallocene compound and a cocatalyst; (B) a support catalyst system comprising the product of support material, cocatalyst(s) and the inventive metallocene compound; and (C) a polymerization process comprising contacting under polymerization conditions monomer(s) and the catalyst composition.
