Title (EN) USE OF A CYCLODEXTRIN POLYCONDENSATE OR A COMPOSITION COMPRISING SUCH A POLYCONDENSATE, AS A CAPTURING AGENT
(FR) UTILISATION D'UN POLYCONDENSAT DE CYCLODEXTRINE OU D'UNE COMPOSITION COMPRENANT UN TEL POLYCONDENSAT, COMME AGENT DE CAPTURE
Abstract:
(EN) The invention concerns 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).
(FR) L'invention se rapporte à l'utilisation d'un polycondensat de cyclodextrine(s), ou d'une composition comprenant au moins un polycondensat de cyclodextrine(s), en tant qu'agent de capture d'au moins une substance choisie parmi un élément métallique et une molécule organique présentant un coefficient de partage octanol/eau, noté Log Kow, supérieur ou égal à 2, le polycondensat de cyclodextrine(s) étant obtenu par la réaction des composés (A) à (C) suivants: (A) au moins une cyclodextrine, (B) au moins un acide polycarboxylique, linéaire, ramifié ou cyclique, saturé, insaturé ou aromatique, et (C) au moins un copolymère d'éthylène et d'alcool vinylique (EVOH).
