    摘要： The present invention concerns a process for producing a container having at least one layer and a top layer, wherein the layer contains polycarbonate and the top layer contains polyarylethersulfone or polyarylsulfone, characterised in that a) polycarbonate is melted on an extruder at 230-320° C., b) polyarylethersulfone or polyarylsulfone is melted on a further extruder, c) the melts obtained from steps a) and b) are shaped by coextrusion into a tube, which is then enclosed in a mould, d) the extrudate is inflated inside the mould and pressed against the wall of the mould, forming the shape of the container, and e) the container obtained from d) is trimmed and cooled, such containers and the use of the containers as bottles or medical devices.

    摘要： A process for making a high molecular weight (co)polycarbonate resin is disclosed. The process entails (i) obtaining at least one member selected from the group low molecular weight residue (weight average molecular weight 15,000 to 30,000) of aromatic (co)polycarbonate production, waste of (co)polycarbonate production, remainders of (co)polycarbonate production and (co)polycarbonate recyclate (ii) melting the said member in a suitable vessel to obtain a melt and (iii) feeding the melt into a reactor optionally along with at least one bisphenol or oligocarbonate having terminal OH groups and further optionally with a transesterification catalyst, and (iv) subjecting the melt to transesterification reaction at a temperature of 250 to 350° C., at a pressure below 5 mbar and residence time of 0.02-4 hours.
