Title (DE) VERFAHREN ZUR HERSTELLUNG VON ESTERPOLYOLE ENTHALTENDEN REAKTIONSMISCHUNGEN
(EN) PROCESS FOR MANUFACTURING REACTION MIXTURES CONTAINING ESTER POLYOLS
(FR) PROCEDE DE FABRICATION DE MELANGES REACTIONNELS RENFERMANT DES ESTERPOLYOLS
Abstract:
(DE) Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von vergleichsweise niedrigviskosen Esterpolyolen enthaltenden Reaktionsmischungen durch Umsetzung von epoxidierten Estern und/oder Alkoholen mit Carbonsäuren sowie die nach diesem Verfahren herstellbare Mischungen von Esterpolyolen, die in Nachbarstellung zu freien Hydroxylgruppen Estergruppen aufweisen.
(EN) The object of the present invention is a process for manufacturing reaction mixtures containing comparatively low-viscosity ester polyols by the reaction of epoxy esters and/or alcohols with carboxylic acids and the mixtures of ester polyols producible by this process having ester groups adjacent to free hydroxyl groups.
(FR) L'invention a pour objet un procédé de fabrication de mélanges réactionnels renfermant des esterpolyols de viscosité relativement faible, par réaction d'esters et/ou d'alcools époxydés avec des acides carboxyliques, ainsi que les mélanges d'esterpolyols obtenus selon ce procédé, présentant des groupes ester en position voisine des groupes hydroxyles libres.
