INSOLUBLE POLYMERIC MATERIAL WITH CONDENSED REAGENT SITES, IN PARTICULAR OF THE ANHYDRIDE GROUP OR ACTIVE ESTER TYPE, PROCESS FOR PREPARING THE SAME AND APPLICATION OF SUCH MATERIAL

摘要

The subject of the present invention is a polymer material with reactive sites, insoluble in particular in aqueous media, characterized in that it consists of a chemically inert and crosslinked polymer or insoluble in particular in aqueous media, onto which is grafted a monomer comprising at least one carboxyl group and / or a polymer of this monomer, all or part of the carboxyl groups of this crosslinked or insoluble and grafted polymer being converted into condensed groups which are more reactive than the corresponding carboxyl groups. It also relates to a process for preparing this material and to applications thereof.
