Abstract
A method for isolating polymer resins from organic solvents is provided wherein the organic solvent is vaporized in a separation medium comprised of water and an organic anti-solvent for said polymer without significant vaporization of the organic anti-solvent. The polymer precipitates as a powder without high-speed, high-shear agitation and without the formation of a sticky globular mass.
