Abstract

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.
