ABSTRACT:
A method of isolating polymer resins from organic solvents is provided wherein the organic solvent is volatilized in the presence of an aqueous slurry of solid polymer particles of a particular size which provide agglomeration sites for the polymer resin within solution. The process can function continuously with various polymers including polycarbonates, polystyrene, polyetherimides, polyphenylene ethers, polyesters, etc.
