The present invention relates to a process for the continuous conversion of polycarbonate based on >/=80 mol% of bisphenol A from a solution in CH2Cl2 into partially crystalline, free-flowing granules with evaporation of the solvent in a device for mixing with continuous or batchwise removal of granules, which process is characterised in that the polycarbonate solution is added to partially crystalline polycarbonate in the device, and the continuously mixed, partially crystalline granules have a CH2Cl2 content of from 21 to 45 % by weight, in particular from 22 to 43 % by weight, preferably from 25 to 40 % by weight. |
