The present invention relates to a method for producing a high-molecular-weight copolymer of polar group-containing allyl monomers comprising 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 &#x2014;OH, &#x2014;OCOR(Rrepresents hydrocarbon group having 1 to 5 carbon atoms), &#x2014;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 an allyl compound using a metal complex of group 10 elements in the periodic system represented by formula (I) as a catalyst. The present invention enables providing a high-molecular-weight copolymer of polar group-containing allyl monomers, which copolymer has a novel structure, is available for various applications and has been considered to be difficult to synthesize by other polymerization methods such as radical polymerization; and a method for producing the same.
