METHOD FOR RECOVERING A POLYMER FROM A LIQUID MEDIUM |
摘要 |
<p>Method for recovering a polymer from a liquid medium (1) substantially containing the polymer and a solvent for the latter, wherein: (a) this liquid medium (1) is injected into a reactor (2) containing a stirred substantially monophase liquid mixture comprising a major fraction by weight of a non-solvent and a minor fraction by weight of a solvent, the mixture having a composition and temperature such that the polymer precipitates therefrom progressively; (b) the polymer is recovered in the form of particles in suspension (5) in a liquid rich in non-solvent; (c) the polymer particles (9) are separated from the liquid.</p> |
