Abstract:
Process for recovering at least one polymer in solution in a solvent by precipitation by means of a non-solvent fluid, whereby the precipitation takes place in a precipitation medium comprising two dispersants of which one [dispersant(I)] has a greater affinity for the non-solvent and the other [dispersant (II)] has a greater affinity for the solvent.
