IPC: C08G65/46
Filed: 1982-10-04
Abstract: A process for preparing high-molecular-weight polyphenylene ethers from monohydric phenols which contain alkyl substituents in the two ortho-positions and possibly in the meta-position, but not in the para-position, by oxidative coupling reaction with oxygen at between 15 and 50 DEG C in the presence of a catalyst complex comprising a metal salt and an organic amine and in the presence of a solvent in the range of 1 : 1 to 20 : 1 parts per weight, based on the monomeric phenol, and if desired in the presence of an activator, the metal ion component of the catalyst being removed from the reaction solution by adding a complexing mercapto compound. Preferred mercapto compounds are aliphatic, aromatic or heterocyclic mono-, di-, tri- or polymercapto compounds, salts of mono-, di-, tri- or polymercapto compounds with alkali metals or alkaline earth metals, thiobisalkylthiols and sodium salts thereof, or bis- or trimercaptotriazine compounds or sodium salts thereof. It is expedient to employ the mercapto compound in such an amount that at least one mole of mercapto groups is present per mole of the heavy metal ion to be removed.
