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

Coupling polymerization of 2,6-dimethylphenol to poly 2,6-dimethyl-1,4-phenylene oxide PPO was carried out in an 1:1 aqueous-chloroform biphasic mixture using Cu-surface active ligand complex catalysts. Bidentate ligands were superior to monodentate ligands in promoting the oxidative co
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
