Process, complex and catalyst for preparation of polyphenylene oxide

Polyphenylene oxides are prepared by the oxidative coupling of monohydroxy aromatic compounds such as 2,6-xylenol in the presence of copper-halide-amine catalysts in which at least part of the amine component is an aromatic diamine such as N,N'-diphenylethylenediamine, N,N'-diphenyl-N,N�...

Zusammenfassung:	Polyphenylene oxides are prepared by the oxidative coupling of monohydroxy aromatic compounds such as 2,6-xylenol in the presence of copper-halide-amine catalysts in which at least part of the amine component is an aromatic diamine such as N,N'-diphenylethylenediamine, N,N'-diphenyl-N,N'-dimethylethylenediamine, N,N'-diphenylpiperazine or N,N,N',N'-tetramethyl-o-phenylenediamine. Other amines preferably present in the catalyst are a tertiary monoamine such as dimethyl-n-butylamine and a secondary monoamine such as di-n-butylamine. These diamines are characterized by a low rate of consumption during polymerization, and the catalysts prepared therefrom are hydrolytically stable.
