Use of a cyclodextrin polycondensate or a composition comprising such a polycondensate, as a capturing agent

Abstract

The use of a cyclodextrin polycondensate or a composition comprising at least one cyclodextrin polycondensate, as an agent for capturing at least one substance chosen from a metal element and an organic molecule having an octanol/water partition coefficient, referred to as Log Kow, greater than or equal to 2, the cyclodextrin polycondensate being obtained by reacting the following compounds (A) to (C): (A) at least one cyclodextrin, (B) at least one linear, branched or cyclic polycarboxylic acid, that is saturated, unsaturated or aromatic, and (C) at least one ethylene vinyl alcohol copolymer (EVOH).

Dependencies are inferred from the claim text.
