MATERIAU COMPRENANT DES POLYAZACYCLOALCANES, GREFFES SUR DES FIBRES DE POLYPROPYLENE, SON PROCEDE DE PREPARATION, ET PROCEDE D'ELIMINATION DE CATIONS METALLIQUES D'UN LIQUIDE

摘要

Material (I) comprises a polyazacycloalkane (II) grafted on polypropylene fibers. An independent claim is included for a preparation of the material constituted by a polyazacycloalkane grafted on the polypropylene fibers, comprising radical polymerization of a polyazacycloalkane monomer carrying a radical polymerizable group, in the presence of polypropylene fibers carrying peroxide and/or hydroperoxide functions, followed by a functionalization of free amino polyazacycloalkane functions and/or a saponification and hydrolysis of ester functions carried by the polyazacycloalkane.
