Catalyst for synthesizing polyolefins

A method for producing copolymers, comprising a process of reacting non-polar olefins with polar olefins under polymerization conditions in the presence of a catalyst composition containing an organometallic compound,

• wherein polar olefins are represented by formula (VII)
• CH2═CR13R14 (VII)
• wherein R13 represents a hydrogen atom or a methyl group;
• R14 represents —COOR15, —CN, —OCOR15, —OR15, —CH2—OCOR15, —CH2OH, —CH2—N(R16)2 or —CH2—Hal, wherein R15 represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms or an aryl group having 6 to 18 carbon atoms;
• R16 represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, an aryl group having 6 to 18 carbon atoms or an alkoxycarbonyl group;
• and Hal represents a halogen atom, and
• wherein the organometallic compound contains bisphosphine monoxide (BPMO) represented by formula (I) and a metal center M comprising elements belonging to Group 10 in the periodic system that forms a complex with BPMO
• R1a, R1b, R2a and R2b may be the same or different with each other, and independently represent a substituted or unsubstituted alkyl group having 1 to 14 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 14 carbon atoms, a substituted or unsubstituted biphenyl group or a substituted or unsubstituted aryl group;
• a pair of R1a and R1b and a pair of R2a and R2b may be bonded to form a ring structure;
• and A1 represents an arylene group, a monocyclic heteroarylene group, a bivalent heterocyclic group, an alkylene group having 1 to 2 carbon atoms, a cycloalkylene group having 3 to 10 carbon atoms, an alkenylene group having 2 to 8 carbon atoms, or a cycloalkenylene group having 3 to 10 carbon atoms.
