ABSTRACT:
A method for producing an aromatic polymer includes polycondensing an aromatic compound represented by formula (I) in the presence of a nickel complex containing a phosphine compound represented by formula (II),wherein, Ar denotes an aromatic ring containing organic group, which aromatic ring may contain an oxygen atom and/or a nitrogen atom; R denotes a monovalent group containing a hydrocarbon group; k is an integer of 1 or more; X denotes an halogen atom, a nitro group or a group represented by —SO3Q, wherein Q denotes a monovalent hydrocarbon group; Y denotes O, S, an imino group, an ethenylene group, or an ethynylene group; n denotes 0 or 1; and M denotes H, —B(OQ1)2, —Si(Q2)3, —Sn(Q3)3or —Z1(Z2)m, wherein Q1denotes H or a monovalent hydrocarbon group; Q2and Q3denote a monovalent hydrocarbon group; Z1denotes a metal atom or a metal ion; Z2denotes a counter ion; and m is an integer of 0 or higher;wherein, R1denotes a monovalent hydrocarbon group, and R2denotes a divalent hydrocarbon group.
