Title (EN) CARBON DIOXIDE AS A CATALYST QUENCH AGENT IN SOLUTION POLYMERIZATION, AND PRODUCTS MADE THEREFROM
(FR) DIOXYDE DE CARBONE EN TANT QU'AGENT DE DÉSACTIVATION DE CATALYSEUR EN POLYMÉRISATION EN SOLUTION, ET PRODUITS FABRIQUÉS À PARTIR DE CE DERNIER
Abstract:
(EN) A method for making a polymer, having the steps of (a) polymerizing one or more monomers in the presence of a solvent and a catalyst to form a reaction product; (b) removing an effluent from the reaction product, where the effluent comprises an active catalyst and one or more unreacted monomers; (c) combining a quench, comprising carbon dioxide, with the effluent to form a quenched polymer stream, having a carboxyl metal complex; and (d) recovering a polymer from the quenched polymer stream.
(FR) L'invention concerne un procédé de fabrication d'un polymère, comprenant les étapes consistant (a) à polymériser un ou plusieurs monomères en présence d'un solvant et d'un catalyseur pour former un produit de réaction ; (b) à éliminer un effluent du produit de réaction, l'effluent comprenant un catalyseur actif et un ou plusieurs monomères n'ayant pas réagi ; (c) à combiner un agent de désactivation, comprenant du dioxyde de carbone, avec l'effluent pour former un flux de polymère désactivé, ayant un complexe de métal carboxyle ; et (d) à récupérer un polymère à partir du flux de polymère désactivé.
