| titleOfInvention | Process for stabilising poly(phenylene ether) solutions |
| abstract | The invention relates to a process for producing high molecular weight polyphenylene ethers from alkyl-substituted monohydric phenols, by oxidative coupling reaction with oxygen in the presence of a catalyst complex composed of a copper salt and an organic amine and then stopping the reaction and removing the metal component of the catalyst by adding chelating and / or salt-forming agents , the polymer solution optionally in amounts of 0.1 to 100 mmol and optionally in 1 to 20% aqueous solutions with compounds of the general structure: wherein R 2 and R 3 may be the same or different and OH, NH 2 or NHR 5 , with R 5 may be alkyl, cycloalkyl and SH groups, and wherein R 1 and R 4 may also be the same or can be different and hydrogen atoms, alkyl, cycloalkyl, aryl, carbonyl, carboxyl, carboxyalkyl, nitrile groups can be treated. |
