Polycarbonate Manufacturing Method |
| abstract |
The present invention provides a method for isolating polycarbonate prepared by a phase interfacial process from a solution in an organic solvent, comprising the following steps:n n n (a) evaporating the organic solvent to obtain a polycarbonate content of 90 to 99.95% by weight,n n n (b) optionally mixing the blowing agent with the melt obtained in step (a),n n n (c) degassing by feeding the melt obtained from (a) and optionally (b) through the inlet to the separation vessel.n n n The process is characterized in that in the degassing according to step (c) the melt is divided by a inlet into a partial stream of 0.1 to 20 kg / hour, and on entering the inlet the melt is supersaturated with volatile components at temperatures of at least 1 bar and at temperatures of 250 ° C. to 340 ° C. And the pressure in the separation vessel is 0.1 to 20 mbar. |
