A process for modified-polymer production by which a high-purity modified polymer can be obtained in a short time. The process comprises chemically modifying a polymer in a supercritical fluid or high-temperature high-pressure fluid to give a modified polymer in which part or all of the monomer units constituting the unmodified polymer have been chemically modified.
L'invention concerne un procédé de production de polymère modifié permettant d'obtenir rapidement un polymère modifié de grande pureté. Le procédé décrit dans cette invention consiste à transformer chimiquement un polymère en un fluide supercritique ou fluide haute pression haute température, afin d'obtenir un polymère modifié dans lequel toutes ou partie des unités monomères constituant le polymère non modifié ont été chimiquement transformées.
