Title:
CATALYSTS FOR OLEFIN POLYMERIZATION, PROCESS FOR PRODUCTION OF OLEFIN POLYMERS, OLEFIN COPOLYMERS, NOVEL TRANSITION METAL COMPOUNDS, AND PROCESS FOR PRODUCTION OF TRANSITION METAL COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2006/022355
Kind Code:
A1
Abstract:
[PROBLEMS] To provide catalysts for olefin polymerization which are excellent in olefin polymerization performance and can give polyolefins having excellent properties. [MEANS FOR SOLVING PROBLEMS] Catalysts for the polymerization of olefins, characterized by comprising (A) a transition metal compound represented by the general formula (I) and (B) at least one compound selected from the group consisting of (B-1) organometallic compounds, (B-2) organoaluminum oxy compounds, and (B-3) compounds capable of reacting with the compound (A) to form an ion pair: (I) wherein M is a transition metal atom selected from among Group 4-6 metals of the periodic table; two of R1 to R4 which are adjacent to each other and the carbon atoms to which the two are bonded are united to form a ring; the others of R1 to R4, R5 to R8, and X are each an atom or a group selected from among hydrogen, halogeno, hydrocarbon groups, halogenated hydrocarbon groups, oxygen -containing groups, and nitrogen-containing groups; Q is -O-, -S-, -NRa-, or -PRb- (wherein Ra and Rb are each hydrogen or a hydrocarbon group); Y is a neutral ligand having an electron -donating group; m is a number satisfying the valence of M; and n is an integer of 0 to 3.
