Title (EN) METHOD FOR ABSORBING LIQUIDS INTO SILICONE-CONTAINING POLYMERS
(FR) PROCÉDÉ D'ABSORPTION DE LIQUIDES DANS DES POLYMÈRES CONTENANT DE LA SILICONE
(DE) VERFAHREN ZUR ABSORPTION VON FLÜSSIGKEITEN IN SILICON-HALTIGE POLYMERE
Abstract:
(EN) The invention relates to a method for absorbing liquids (F) containing compounds (V) selected from water and alkanols, the oxygen content of which in weight percentage is at least 27%, said content being present in the form of hydroxy groups or hydroxy and ether groups, into a solid silicone-containing polymer (P) which contains at least one siloxane unit of the general formula I (R1 b(X)cSiO[4-(b+c)] /2) and no units or at least one unit of the general formula II (R2 aSiO(4-a)/2), in which R1, R2, X, a, b, and c have the meanings described in claim 1, wherein the liquids (F) are brought into contact with the solid silicone-containing polymer (P).
(FR) L'invention concerne un procédé d'absorption de liquides (F) qui contiennent des composés (V) qui sont choisis parmi l'eau et des alcanols dont la proportion en poids d'oxygène qui est présent sous forme de groupes hydroxy ou hydroxy et éther vaut au moins 27 %, dans un polymère (P) contenant de la silicone solide qui contient au moins un motif siloxane de formule générale I (R1 b(X)cSiO[4-(b+c)] /2) et aucun ou au moins un motif de formule générale II (R2 aSiO(4-a)/2), dans lesquelles R1, R2, X, a, b et c présentent les significations décrites dans la revendication 1. Selon le procédé, les liquides (F) sont amenés en contact avec le polymère (P) contenant de la silicone solide.
(DE) Gegenstand der Erfindung ist ein Verfahren zur Absorption von Flüssigkeiten (F), die Verbindungen (V) enthalten, die ausgewählt werden aus Wässer und Alkanolen, deren Gewichtsanteil an Sauerstoff, der in Form von Hydroxy- oder Hydroxy- und Ethergruppen vorliegt, mindestens 27 % beträgt, in festes Silicon-haltiges Polymer (P), das mindestens eine Siloxaneinheit der allgemeinen Formel I (R1b(X)cSiO[4-(b+c)] /2) und keine oder mindestens eine Einheit der allgemeinen Formel II (R2aSiO(4-a)/2) enthält, worin R1, R2, X, a, b und c die in Anspruch 1 beschriebenen Bedeutungen aufweisen, bei dem die Flüssigkeiten (F) mit dem festen Silicon-haltigen Polymer (P) in Kontakt gebracht werden.
