Abstract: 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.

Abstract: The present invention relates to a method for producing a homopolymer of olefin represented by formula (1): CH2═CHR1 (R1 is a hydrogen atom or hydrocarbon group having 1 to 20 carbon atoms) or a copolymer of two or more thereof or a method for producing a copolymer of olefin represented by formula (1) with olefin containing a polar group represented by formula (2): CH2═CHR2R3 (R2 is a hydrogen atom or methyl group, R3 is —COOR12, —CN, —OCOR12, —OR12, —CH2—OCOR12, —CH2OH, —CH2—N(R13)2 or —CH2-Hal (R12, R13 and Hal have the same meanings as stated in the description), using as a catalyst a metal complex of group 10 elements in the periodic system typified by the structure represented by formula 1 (“Men” represents a menthyl group and “Me” represents a methyl group). The present invention enables the production of high molecular weight polymers of the polar group-containing monomers such as polar group-containing allyl compounds.
