Title (EN) METHOD FOR PREPARING POLYETHER CARBONATES
(FR) PROCÉDÉ DE PRÉPARATION DE POLYÉTHER CARBONATES
Abstract:
(EN) The present invention relates to a method for preparing a high molecular weight polyether carbonate, by reacting an epoxide and carbon dioxide in the presence of a catalyst of formula (I), and a double metal cyanide (DMC) catalyst. The catalyst of formula (I) has the following structure.
(FR) La présente invention concerne un procédé de préparation d'un polyéther carbonate à haut poids moléculaire par réaction d'un époxyde et de dioxyde de carbone en présence d'un catalyseur de formule (I) et d'un catalyseur à base de cyanure métallique double (DMC). Le catalyseur de formule (I) présente la structure suivante :
