Abstract:
In a device for removing volatile components from a polymer solution comprising a container comprising:(i) an inlet for the polymer solution; (ii) an outlet for the volatile components; (iii) an outflow for the polymer solution from which the volatile components have been removed; (iv) a heat exchange unit arranged inside the container with a central receiving zone for the polymer solution, the central receiving zone connected to the container inlet; and (v) a product zone to receive the polymer solution from which the volatile components have been removed, wherein the heat exchange unit has a plurality of channels forming a heat exchange zone and connecting the central receiving zone to the product zone, the improvement comprising including a heating means to heat the heat exchange unit and the channels, wherein the channels have a length of 1.0 to 40 cm, a height, constant over the length thereof, of 1.3 to 13 mm and a width of 1 to 10 cm at entry of the channels and wherein the width of the channels at least triples between the entry and the exit thereof to the product zone.
