    摘要： A process for the production of a bifunctional phenylene ether oligomer compound having no amine adduct represented by the formula (1), which process comprises oxidatively polymerizing a bivalent phenol and a monovalent phenol in the presence of a copper-containing catalyst and a tertiary amine, a secondary amine having a secondary alkyl group, a tertiary alkyl group or an aryl group, or a mixture of both, [Chemical Formula 1] wherein R1, R2, R3, R7, R8, R9 and R10 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, R4, R5, R6, R11 and R12 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, and each of m and n is an integer of from 0 to 25, provided that at least one of a and b is not 0.
