摘要： Process for recovering a polymer by injection of steam, and optionally liquid water, into a solution of this polymer comprising a polar aprotic organic solvent (PAOS) that has an azeotrope with water and an apolar organic compound that is miscible with the PAOS and immiscible with water and that acts as a phase separation agent (PSA), the boiling point of which is below that of the water/PAOS azeotrope, the amount of steam injected being sufficient to give rise to the substantial removal of the PSA via stripping and that of the PAOS via azeotropic distillation, and the total amount of water being sufficient to give rise to the precipitation of the polymer, this process being characterized in that the polymer solution also comprises an alcohol, at least during the precipitation of the polymer.
