Abstract

Si preparano perfluoropoliossialchileni perossidici, con rese elevate, effettuando la fotoossidazione del tetrafluoroetilene con ossigeno molecolare, mediante radiazioni U.V., operando in presenza di pentafluorocloroetano quale solvente del tetrafluoroetilene.Si possono così ottenere perfluoropoliossialchileni perossidici di viscosità a 20°C compresa tra 300.000 e 8.000.000 cSt. e dotati di contenuto perossidico non superiore a 4. Tali perfluoropoliossialchileni forniscono, tramite riduzione chimica, perfluoropoliossialchileni dotati di funzionalità superiore a 1,9 ed al tempo stesso di peso molecolare elevato.
