Title
(EN) CATIONIC POLYMERIZATION IN CARBON DIOXIDE
(FR) POLYMERISATION CATIONIQUE EN PRESENCE DE DIOXYDE DE CARBONE
Abstract
(EN)
The present invention provides a method of carrying out the cationic polymerization of a monomer in carbon dioxide. The method includes the steps of (a) providing a reaction mixture comprising carbon dioxide, a monomer, a catalyst and a cationic polymerization initiator, wherein the cationic polymerization initiator is capable of initiating the cationic polymerization of the monomer; (b) polymerizing the monomer in the reaction mixture to form a polymer.
(FR)
La présente invention concerne un procédé de polymérisation cationique d'un monomère en présence de dioxyde de carbone. Le procédé consiste: a) à réaliser un mélange de réaction comprenant du dioxyde de carbone, un monomère, un catalyseur et un amorceur de polymérisation cationique capable d'amorcer la polymérisation cationique, et b) à polymériser le monomère dans le mélange de réaction pour constituer un polymère.
