摘要： A process for producing an aliphatic-aromatic polycarbonate is disclosed. The process comprise (A) reacting in an anhydrous neutral solvent (i) an oligocarbonate of diphenol with (ii) an aliphatic dicarboxylic acid, and (B) eliminating the hydrogen chloride and carbon dioxide by-products. The oligocarbonate of diphenol is characterized in that it is terminated by chlorocarbonic acid ester groups. The resins thus prepared are readily molded conventionally.

摘要： A process is disclosed for the purification of lacquer-and optionally dye and metal- containing waste of thermoplastic aromatic polycarbonates and/or thermoplastic aromatic polyester carbonates. The waste which result upon the production of moldings, such as audio compact discs, lenses for spectacles or head-lamp reflectors is processed in accordance with the invention to yield useful resin suitable for reprocessing as a molding resin. In accordance with the process, the waste is first size-reduced and then heated with acid to the reflux temperature while stirring. After a water wash there is followed a drying step. In accordance with the process, in instances where the waste does not originally contain metal, the metal in powder form is added before the acid treatment.

摘要： A process for the production of 2,2-bis(4-hydroxyphenyl)propane (BPA) is disclosed. The process that entails reacting acetone with phenol in the presence of cross-linked sulfonated polystyrene resins is characterised in that BPA is separated from the reaction solution downstream of the reaction unit by means of a multi-stage vacuum distillation and a subsequent single- or multi-stage layer crystallisation. The by-product stream with accumulated by-products is returned downstream of the reaction unit.
