Abstract:
The present invention relates to the use of an aromatic polycarbonate prepared by the transesterification of a bisphenol and a diaryl carbonate and having a viscosity average molecular weight, Mv, of from 22000 to 32000 g/mol, a polydispersity, defined as Mw/Mn, of from 1.8-3.2, a melt-flow index of from 3.0-10 g/10 min as determined in accordance with ASTM D 1238 (1.2 kg, 300° C.), an amount of Fries branching of from 750 to 2500 ppm, for the manufacture of bottles having a volume of at least 15 liter by means of an injection blow moulding or an extrusion blow moulding process.
