A process for reducing the carbonyl group of a polyketone consisting of a carbon monoxide ethylene-based copolymer, comprising reacting a blend of carbon monoxide ethylene-based polymer with a metal alkoxide in a molten condition in proportions to provide a novel polyalcohol. This chemical modification changes the properties of the carbon monoxide ethylene-based polymers and renders them eligible for uses for which the original polymers were not or not very suitable.
La présente invention concerne un procédé de réduction du groupe carbonyle d'un polycétone constitué d'un copolymère éthylène-monoxyde de carbone, consistant à faire réagir un mélange de polymère éthylène-monoxyde de carbone avec un alcoxyde métallique en fusion dans des proportions suffisantes pour former un nouveau polyalcool. Cette modification chimique modifie les propriétés des polymères éthylène-monoxyde de carbone et les rend utilisables dans les cas où les polymères d'origine ne conviennent pas ou ne sont pas très appropriés.
