摘要： A process for the continuous splitting of polycarbonates into dihydroxy compounds and carbonic acid esters is disclosed. Accordingly there are reacted in a distillation column a polycarbonate resin and a monohydroxy compound in the presence of a transesterification catalyst. The polycarbonate, in molten form or as a solute, is continuously fed into the upper part of the column and the monohydroxy compound in vapor phase is continuously fed into the lower part of the column. The resulting carbonic acid ester and dihydroxy compounds are continuously being removed from the column. The process is eminently suitable for the recycling of polycarbonate waste.
