Title:
METHOD FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2013/140991
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing an olefin polymer having a high melting point and high molecular weight even under industrially feasible high-temperature conditions. [Solution] A method for producing an olefin polymer, characterized by comprising polymerizing a C2 or higher olefin in the presence of an olefin-polymerizing catalyst, the catalyst including: (A) a cross-linked metallocene compound represented by general formula [1]; and (B) at least one species of compound selected from organoaluminumoxy compounds, organoaluminum compounds, and the like. (In formula [1], R1-R4 represent hydrocarbon groups or the like; R5-R9 represent hydrogen atoms, halogen atoms, or the like; R10-R11 represent hydrogen atoms or the like; R12 represents a hydrocarbon group or the like; Y represents a carbon atom or the like; M represents Zr or the like; Y represents a carbon atom or the like; Q represents a halogen atom or the like; and j represents an integer 1-4.)
