Title (EN) METHOD FOR PRODUCING OLIGOMERS FOR PRODUCING POLYCARBONATES
(FR) PROCÉDÉ DE PRODUCTION D'OLIGOMÈRES POUR LA PRODUCTION DE POLYCARBONATES
Abstract:
(EN) A process for producing an oligomer comprising contacting a alkylaryl carbonate and a dihydroxy compound in a reaction zone in the presence of an oligomerization catalyst under oligomerization conditions to form the oligomer wherein the molar ratio of dihydroxy compound to alkylaryl carbonate in the reaction zone is at least 2:1.
(FR) L'invention concerne un procédé de production d'un oligomère comprenant la mise en contact d'un carbonate d'alkylaryle et d'un composé dihydroxy dans une zone de réaction en présence d'un catalyseur d'oligomérisation dans des conditions d'oligomérisation pour former l'oligomère, le rapport molaire du composé dihydroxy sur le carbonate d'alkylaryle dans la zone de réaction étant d'au moins 2/1.
