| abstract |
Polymer product, such as a polyester resin, is recovered in finely divided form from a polymer product/solvent solution by the addition of the solution to a hot, non-boiling water phase with non-shearing agitation of resulting composition of the water, polymer product, and solvent under conditions which give rise to turbulence in the composition. The solvent, which has a lower boiling point than the temperature at which the hot water is maintained, boils off from the polymer product, solvent, and water composition and leaves the desired, finely divided, polymer product admixed in the water phase. The product can be recovered by filtration or other suitable separation technique. |
