    摘要: The present invention relates to a method for separation of a polymer from a polymer solution or dispersion, wherein (i) a solution or dispersion of a polymer in an organic solvent is atomized by being brought into contact with water vapour in an atomizer container; (ii) the mixture obtained in the atomizer container is routed into a polymer degasification container and flows through same, wherein the organic solvent present in the polymer particles is driven at least partially out of the polymer particles due to the thermal contact between the polymer particles and the water vapour and transitions into the gas phase (iii) the mixture exiting from the polymer degasification container is routed into a phase separator (1) and the organic solvent present in the gas phase is separated from the polymer particles and the condensed water vapour; and (iv) the polymer particles and the condensed water vapour are routed into a phase separator (2) in order to separate the polymer particles from the condensed water vapour.
