Verfahren und Vorrichtung zur Entfernung flüchtiger Bestandteile aus Polymermassen

摘要

The invention relates to a method and device for removing volatile components, especially solvents, monomers or oligomers, from polymer materials or polymer solutions by evaporating the volatile components from the pre-heated polymer materials in the form of free falling films, strands (4) or foaming liquids in an evaporator system (1). According to the inventive method, once partial or full degassing of the volatile components has occurred in the degassing chamber (9) of the evaporator system (1), the degassed polymer material (4) is directly received by a discharge conveyor device (5) on the lower end of the vaporization system (1), whereby the polymer is prevented from coming into contact with the inner wall of the evaporator system (1).
