| titleOfInvention | High-purity polycarbonates and process for their production |
| abstract | A process is described for the production of polycarbonate with a foreign particle index of less than 2.5 È 10 · 4 · mum · 2 · / g or an alkali salt of less than 50 ppb according to the phase interface process, in which the solution containing polycarbonate is mixed with an aqueous washing liquid washed, the washing liquid is separated off and the solvent is evaporated, characterized in that the mixture of organic solution and residual washing liquid obtained after the washing liquid has been separated is heated until a clear solution is obtained and filtered to remove solids. |
