CATALYST FOR OLEFIN POLYMERIZATION, METHOD FOR PRODUCING OLEFIN POLYMER, METHOD FOR PRODUCING PROPYLENE COPOLYMER, PROPYLENE POLYMER, PROPYLENE POLYMER COMPOSITION, AND USE OF THOSE

Document Type and Number:

WIPO Patent Application WO/2006/123759

Kind Code:

A1

Abstract:

Disclosed is a catalyst for olefin polymerization composed of a crosslinked metallocene compound (A-1) represented by the general formula [1-1] below and at least one or more compounds (b) selected from organic aluminum oxy compounds (b-1), compounds (b-2) forming an ion pair, and organic aluminum compounds (b-3). [1-1] (In the general formula [1-1], R¹, R², R³, R⁴, R⁵, R⁸, R⁹ and R¹² respectively represent one selected from a hydrogen atom, a hydrocarbon group and a silicon-containing group; R⁶, R⁷, R¹⁰ and R¹¹ are not hydrogen atoms and respectively represent one selected from a hydrocarbon group and a silicon-containing group; R¹³ and R¹⁴ respectively represent a hydrogen atom, a hydrocarbon group other than a methyl group or the like; M represents Ti, Zr or the like; Y represents carbon or the like; Q represents a halogen or the like; and j represents an integer of 1-4.)
