Abstract

Oppfinnelsen vedrører en fremgangsmåte for fremstilling av spesielle kopolykarbonater fra dihydroksydifenylen i henhold til polykarbonat-fremgangsmåten i smelte der N-alkyl-substituerte piperidiner og morfoliner benyttes som katalysatorer.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a process for the preparation of special copolycarbonates from the dihydroxydiphenylene according to the polycarbonate process in the melt, where N-alkyl-substituted piperidines and morpholines are used as catalysts.
