Abstract

Procedimento per l'ottenimento di polifenileneteri in forma di polveri aventi dimensione media dei granuli compresa tra 100 e 500 ?m oltre il 70 %, preferibilmente oltre l'80%, dei granuli con dimensioni comprese in un intervallo di 200 ?m e un contenuto massimo inferiore a 0,1% di polveri con dimensioni dei granuli inferiori a 10 ?m, comprendente in successione:(a) far reagire uno o più fenoli sostituiti mediante policondensazione ossidativa con ossigeno, in un solvente costituito da una miscela di toluene e metanolo, in presenza di un complesso formato da un sale rameico non-basico e da morfolina a un suo derivato C-sostituito, ad una temperatura compresa tra 50 e 70° C, fino ad ottenere una dispersione del polifenilenetere nel solvente di reazione, e (b) recuperare il polifenilenetere così ottenuto.
