Abstract

Procédé perfectionné pour copolymériser du tétrahydrofuranne et un oxyde d'alcoylène ou un acétal cyclique. On prépare un copolyéther glycol à groupes terminaux ester en copolymérisant du tétrahydrofuranne et un oxyde d'alcoylène ou un acétal Cyclique dans un milieu de réaction qui contient, en plus du tétrahydrofuranne et de l'oxyde d'alcoylène ou de l'acétal cyclique : un catalyseur polymère contenant des groupes acide alpha -fluoro sulfonique, et un progéniteur d'ion acylium tel que l'anhydride acétique. Application à la préparation de polyuréthanes.
