Oxidative polymerization of 2,6-dimethylphenol catalyzed by copper-amine complexes provides a convenient method to synthesize poly(2,6-dimethyl-1,4- phenylene ether) (PPE). Based on the mechanism of polymerization and depolymerization of PPE, it was anticipated that structure-defined PPE copolymers should be obtained, such as alternating copolymers or block copolymers. In this work, the behavior of polymerization, structure and composition of the resulting copolymers were investigated. The depolymerization of PPE with 2,6-difluorophenol using a CuCl2/N,N,N′N′- tetramethylethylenediamine catalyst was accomplished to produce the corresponding copolymer. Structural analyses using 1H-NMR, 13C-NMR, and 19F-NMR revealed that the polymer consisted of both oxy-2,6-dimethyl-l,4-phenylene units and oxy-2,6-difluoro-l,4-phenylene units. Attempts to control the composition of the comonomers will be discussed.
