Title (EN) IMPROVED POLYMER POLYOL QUALITY
(FR) QUALITÉ AMÉLIORÉE DE POLYOL POLYMÈRE
Abstract:
(EN) This invention relates to a process for preparing a stable low viscosity polymer polyol having a solids content of at least about 30% by weight. This process is particularly suitable for restarting the process of production after any reactor shutdown (planned or unplanned).
(FR) La présente invention concerne un procédé de préparation d'un polyol polymère stable de viscosité faible présentant une teneur en solides d'au moins environ 30 % en poids. Ce procédé est particulièrement approprié pour redémarrer le procédé de production après l'arrêt de n'importe quel réacteur (planifié ou non planifié).
