| titleOfInvention | Isolation Method of Partially Crystalline Polycarbonate Powder |
| abstract | The present invention evaporates the organic solvent of the polycarbonate solution, optionally in a heat exchanger with mixing aquatic groups or in a holding tube with mixing aquatic, and concentrates the pastey mixture of concentrated solution, solvent vapor and optionally water in a separator. Provided are methods for isolating partially crystalline polycarbonate powders or oligocarbonate powders that separate. In this method, the solvent medium is condensed in a heat exchanger downstream from the separator. The solvent is evaporated by indirect heat input through the heat exchanger wall in the heat exchanger, and the evaporation is effected by preheating the polycarbonate or oligocarbonate solution in the upstream heat exchanger, introducing a submersible or both. I can promote it. |
