Abstract
A device can be used for the degassing of a two-component multiphase polymer-monomer material. A corresponding degassing extruder contains the degassing device. The device for degassing contains at least one nozzle part having a convergent geometry, at least one constant part, and at least one diffusor part having a divergent geometry. The diffusor part contains at least three zones each having a divergent geometry, and the opening angles of the zones are specifically adapted in order to improve the separation of components of the polymer material. A process for degassing a polymer material uses the degassing device.
