1. A method for producing a copolymer of polar group-containing allyl monomers having monomer units represented by formulae (3) and (4) (in the formulae, R1 represents a hydrogen atom or hydrocarbon group having 1 to 6 carbon atoms; R2 represents —OH, —OCOR3 (R3 represents hydrocarbon group having 1 to 5 carbon atoms), —N(R4)2 (R4 represents a hydrogen atom, hydrocarbon group having 1 to 5 carbon atoms, aromatic residue having 6 to 18 carbon atoms or —COOR10 (R10 represents hydrocarbon group having 1 to 10 carbon atoms or aromatic residue having 6 to 10 carbon atoms) and two R4s may be the same or different from each other) or a halogen atom; and n and m are a value representing the molar ratio of each of the monomer units, comprising copolymerization of olefin represented by formula (1)
CH2═CHR1 (1) (in the formula, R1 has the same meaning as described above) and an allyl compound represented by formula (2)
CH2═CHCH2R2 (2) (in the formula, R2 has the same meaning as described above) using as a catalyst a metal complex represented by formula (C1) (in the formula, M represents a metal atom of group 10 element in the periodic system; X represents a phosphorous atom (P) or an arsenic atom (As); R5 represents a hydrogen atom or hydrocarbon group having 1 to 30 carbon atoms which may be substituted by one or more groups selected from a halogen atom, alkoxy group, aryloxy group and acyloxy group; Y, R6 and R7 independently represent a hydrogen atom, alkoxy group, aryloxy group, silyl group, amino group or hydrocarbon group having 1 to 30 carbon atoms which may be substituted by one or more groups selected from a halogen atom, alkoxy group and aryloxy group; and R6 and R7 may bond to each other to form a ring structure; Q represents a bivalent group indicated in the brackets of Z[—S(═O)2—O-]M, Z[—C(═O)—O-]M, Z[—P(═O)(—OH)—O-]M or Z[—S-]M, wherein Z and M at the beginning and at the end of the formulae are described to show the coupling direction of the groups; Z represents a hydrogen atom or a hydrocarbon group having 1 to 40 carbon atoms which may be substituted by one or more groups selected from a halogen atom, alkoxy group and aryloxy group; Y and Z may bond to each other to form a ring structure; R6 and/or R7 may bond to Y to form a ring structure; L represents an electron-donating ligand and q is 0, ½, 1 or 2). |
