DIOXYDE DE CARBONE EN TANT QU'AGENT DE DÉSACTIVATION DE CATALYSEUR EN POLYMÉRISATION EN SOLUTION, ET PRODUITS FABRIQUÉS À PARTIR DE CE DERNIER

摘要

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.
