Title:
POLYMERIZATION CATALYSTS FOR OLEFINS AND PROCESS FOR THE PRODUCTION OF OLEFIN POLYMERS
Document Type and Number:
WIPO Patent Application WO/2003/101936
Kind Code:
A1
Abstract:
Transition metal complexes obtained by reacting a ligand represented by the general formula (1): (1) [wherein R1 to R3 are each independently hydrogen, substituted or unsubstituted alkyl having 1 to 10 carbon atoms, substituted or unsubstituted aryl having 6 to 20 carbon atoms, or the like; A1 to A3 are each a Group 15 element of the periodic table; and R2 and R3 may be united to form a ring] with a transition metal compound represented by the general formula (2): (2) [wherein M is a Group 4 transition metal of the periodic table; X1, X2, X3 and X4 are each independently hydrogen, halogeno, substituted or unsubstituted alkyl having 1 to 10 carbon atoms, substituted or unsubstituted alkoxy having 1 to 10 carbon atoms, or the like; n is an integer of 0 or 1; and two or more of X1, X2, X3 and X4 may be united to form a ring]; polymerization catalysts for olefins containing the transition metal complexes; and a process for the production of olefin polymers by using the catalysts.
