Beschreibung
Zusammenfassung:	An aromatic carbonate process comprising contacting a phenol, carbon monoxide, a base, a Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium or platinum having an oxidation state of plus one. The resulting aromatic mono- and polycarbonates are useful in the preparation of polycarbonates or as polycarbonates, per se, respectively, which can be molded or formed into films, sheets, fibers, laminates or reinforced plastics by conventional techniques.
