Abstract

Inventia de fata se refera la un procedeu de obtinere a polifenilelnoxizilor prin reactia de polimerizare oxidativa a fenolilor 2,6-sau ,2,4-dialchil-sau diaril-disubstituiti în prezenta catalizatorilor-complexi de saruri cupru-amine, în mediu de amestec de benzen-alcool izopropilic în raport de 8: 2..2:8, polimerul fiind filtrat si spalat cu solvent avand compozitia identica cu cea utilizata la faza de sinteza.The present invention relates to a process for the preparation of polyphenylene oxides by the oxidative polymerization reaction of 2,6-di-, 2,4-dialkyl- or diaryl-disubstituted phenols in the presence of copper-amine salt complex catalysts in mixture medium of benzene-isopropyl alcohol in an 8: 2..2: 8 ratio, the polymer being filtered and washed with solvent having the same composition as used in the synthesis phase.
