Abstract

L'invention concerne un procédé d'isolement d'un polymère à bas poids moléculaire à partir d'une solution du polymère à bas poids moléculaire présentant une viscosité de 5 à 100 000 cps à 30 degrés C et un catalyseur inactivé dans un solvant organique hydrophobe. Le procédé comprend le mélange de la solution contenant le polymère avec de l'eau acide, alcaline ou neutre ou avec un mélange d'eau et d'un solvant organique soluble dans l'eau en présence d'un agent surfactif amphotère cationique non ionique ou d'un agent de floculation à poids moléculaire élevé non ionique ou cationique puis la séparation de la couche organique et de la couche aqueuse et la récupération du polymère. Application de l'invention à la récupération améliorée d'un polymère.
