ABSTRACT:
A devolatilizer, especially suitable for high viscosity polymers, comprising a vacuum chamber into the top of which the polymer is introduced after having passed through a tubular or equivalent heat exchanger, with a low shear mixer located in the vacuum chamber and a pumping device for removing the devolatilized polymer from the bottom of the vacuum chamber. Devolatilization of high viscosity polymers is achieved in this apparatus and method without severe degradation.
