Separating polymeric two component mixtures - dissolving the mixt in a soln. mixt. above point of dissociation, cooling solution below dissociation to produce two phases

摘要

Mixt. is sepd. into its constituents by dissolving in a soln. mixt. comprising a solvent for each of the constituents, above the dissociation temp., cooling the homogeneous soln. below the dissociation temp. to produce two phases which can be sepd. from one another and isolating the constituents in the phases using a known sepg. process. Sepn. of polymeric constituents can be effected without any adsorption or occlusion effects.
