Abstract
The present invention relates to a method for producing a homopolymer of olefin represented by formula (1): CH═CHR(Ris 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): CH═CHRR(Ris a hydrogen atom or methyl group, Ris —COOR, —CN, —OCOR, —OR, —CH—OCOR, —CHOH, —CH—N(R)or —CH-Hal (R, Rand 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.
