Abstract:
1. A method for producing a block copolymer which comprises the step of sequentially reacting two or more aromatic compounds which are selected from aromatic compounds represented by the following general formula (V) and are different in the group Ar, in the presence of a nickel complex containing a phosphine compound represented by the following general formula (I) or a palladium complex containing a phosphine compound represented by the following general formula (II) to thereby form blocks derived from the respective aromatic compounds sequentially, wherein the two or more aromatic compounds are reacted in descending order of parameter of aromatic ring charge, the general formula (V): (wherein Ar represents an organic group having a valence of (2+k) and containing aromatic ring(s), X bonds to the aromatic ring in Ar, R represents a hydrocarbyl group which may be substituted, a hydrocarbyloxy group which may be substituted, a hydrocarbylmercapto group which may be substituted, a hydrocarbylcarbonyl group which may be substituted, a hydrocarbyloxycarbonyl which may be substituted, a hydrocarbylsulfonyl group which may be substituted, a hydrocarbylamino group which may be substituted or a hydrocarbylaminocarbonyl group which may be substituted, k is an integer of 0 or more, in the case of a plurality of R being present, all R may be the same or different, and two Rs may form a ring together, X represents a halogen atom, a nitro group or a group represented by —SO the general formula (I): (wherein R the general formula (II): (wherein R (wherein R (wherein R (wherein the formula (VI) corresponds to the formula (V) in which M-(Y)
