ABSTRACT:
The drying of a polymer solution by the removal of solvent is accomplished by flashing the polymer solution while spraying into a bed of substantially dry polymer particles. The dryer polymer particles coat the partially dried solution polymer droplets, and the remaining solvent is removed by the energy produced from the mechanical agitation of the bed and the passing of a heated inert gas through the polymer bed.
