Abstract

Préparation de copolymères blocs. Selon l'invention, on prépare des copolymères blocs de configuration AB ou ABA en polymérisant anioniquement un composant, en terminant le polymère actif par du soufre ou un episulfure et en complétant la polymérisation de la portion restante par une polymérisation radicalaire. Permet la préparation de copolymères blocs contenant des monomères qui sont généralement considérés comme inappropriés pour une polymérisation anionique.Preparation of block copolymers. According to the invention, block copolymers of AB or ABA configuration are prepared by anionically polymerizing a component, terminating the active polymer with sulfur or an episulfide and completing the polymerization of the remaining portion with radical polymerization. Allows the preparation of block copolymers containing monomers which are generally considered unsuitable for anionic polymerization.
