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 PPE block copolymers should be obtained. In this work, the behavior of polymerization, and the structure of the resulting copolymers were investigated. The depolymerization of PPE with oligo(2,6-difluoro-1,4-phenylene ether) using a CuCl₂/N,N,N′, N′-tetramethylethylenediamine catalyst was accomplished to produce the corresponding copolymer. Structural analyses using NMR, DSC, and XRD revealed that the polymer was a block copolymer. During the depolymerization reaction, an intermediate phenoxyl radical was observed by ESR. The depolymerization with other oligomeric PPE will be discussed.
