摘要： The present invention relates to a method for producing a copolymer of ethylene and a polar group-containing olefin using as a catalyst a metal complex of group 10 elements having a structure represented by formula (C4) and (C5) (in the formula, “Men” represents a menthyl group and “Me” represents a methyl group). The method of the present invention makes it possible to produce a polar group-containing olefin polymer available for various applications, as being a high molecular weight body, which has been difficult to produce, and to produce the polymer in a molecular weight range such that the polymer has good moldability.
