Abstract
Procédé de préparation d'une composition polymère/polyol fluide et stable, caractérisé en ce qu'on polymérise, en présence d'un catalyseur à radicaux libres, un mélange réactionnel comprenant : 1. d'environ 10 à 40 % en poids d'un monomère à insaturation éthylénique ou d'un mélange de tels monomères, 2. d'environ 60 à 90 % en poids d'un polyoxypropylène polyol normalement liquide ayant une masse moléculaire moyenne en nombre d'au moins 400 environ et un indice d'hydroxyle d'environ 20 à 280, lesdits pourcentages en poids de monomère ou de mélange de monomères et de polyol étant exprimés par rapport à leur poids total, et 3. un stabilisant préformé compatible avec le polyol et présent en une proportion suffisante pour stabiliser le polymère/ polyol résultant, le stabilisant étant un copolymère comprenant : a. une portion d'ancrage constituée par un polymère du monomère ou du mélange de monomères définis sous 1 chimiquement fixé sur b. une portion solvatable constituée par un polyoxypropylène ayant une masse moléculaire moyenne en nombre d'au moins 800 environ.
