Claim Text:
1. 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) wherein R 13 represents a hydrogen atom or a methyl group; R 14 represents —COOR 15 , —CN, —OCOR 15 , —OR 15 , —CH 2 —OCOR 15 , —CH 2 OH, —CH 2 —N(R 16 ) 2 or —CH 2 —Hal, wherein R 15 represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms or an aryl group having 6 to 18 carbon atoms; R 16 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 R 1a , R 1b , R 2a and R 2b 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 R 1a and R 1b and a pair of R 2a and R 2b may be bonded to form a ring structure; and A 1 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.
