Catalysis by insoluble polymer Cu complexes was studied for the oxidative polymerization of 2,6-dimethylphenol. The polymerization was heterogeneously catalysed by the insoluble complex. The catalyst was readily recovered by filtration and could be re-used. Compared with the homogeneous system, the
The oxidative coupling polymerization of 2,6-dimethylphenol (DMP) catalysed by copper(II) complexes of N-methylimidazole in toluene/iso-propanol (13/2v/v) or 1,2-dichlorobenzene/methanol (ODCB/MeOH) (13/2 v/v) was investigated. EPR spectra of these complexes indicated that the complex had a mononucl
## Abstract Copper‐(__N,N,N′,N__′‐tetramethylethylenediamine) (tmed) complexes as catalysts in the oxidative‐coupling polymerization of 2,6‐dimethylphenol (DMP) give rise to poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) in high yield, although the formation of the undesired 3,5,3′,5′‐tetramethyldiph
