Abstract

La présente invention concerne des polymères greffés à base de polyalkylène, sensiblement purs, de qualité pharmaceutique, ainsi que leurs procédés de fabrication. Ces procédés consistent à mélanger un oxyde de polyalkylène liquide avec dix à quinze parties équivalentes environ d'un monomère acrylique et un catalyseur adapté, en l'absence d'oxygène, pour former un mélange réactionnel. Le procédé consiste ensuite à récupérer les polymères sensiblement pures à partir du mélange réactionnel. Les polymères obtenus peuvent être davantage purifiés. L'invention concerne également un procédé servant à isoler ou à récupérer des polymères de masse moléculaire élevée à partir d'un système eau-solvant organique.
