Abstract
The present invention relates to a method for producing a high-molecular-weight copolymer of polar group-containing allyl monomers including monomer units represented by formulae (3) and (4) (in the formulae, Rrepresents a hydrogen atom (H) or hydrocarbon group having 1 to 6 carbon atoms; Rrepresents —OH, —OCOR(Rrepresents hydrocarbon group having 1 to 5 carbon atoms), —N(R)(Rrepresents a hydrogen atom or hydrocarbon group having 1 to 5 carbon atoms); and n and m are a value representing the molar ratio of each of the monomer units), which has few branches and unsaturated group at the molecular end, by copolymerizing olefin and a polar group-containing allyl compound using a metal complex of group 10 elements in the periodic system represented by formula (I) as a catalyst.
