MATERIAL MIT POLYAZACYCLOALKANEN, DIE AUF POLYPROPYLENFASERN AUFGESETZT SIND, VERFAHREN ZUR HERSTELLUNG DAVON UND VERFAHREN ZUR ENTFERNUNG VON METALLKATIONEN AUS EINER FLÜSSIGKEIT

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.
