CA 2535067
The invention relates to a cationic poly(ether-urethane) consisting of a) at least one polyetherol, as constituent A; b) at least one tertiary diol containing amine or ammonium, as constituent B; c) at least one diisocyanate, as constituent C; d) and optionally at least one shortstopping agent, as constituent D; the cationic poly(ether-urethane) having an amine value of between 5 and 40. The invention also relates to a method for producing the inventive cationic poly(ether-urethanes), to compositions containing said cationic poly(ether-urethanes) and at least one anionic surfactant, to a method for foam regulation, especially for the suppression of foam or for defoaming, using at least one inventive cationic poly(ether-urethane), and to the use of said cationic poly(ether-urethane) for foam regulation, especially as a foam suppressing agent or a defoaming agent.
La présente invention concerne un poly(éther-uréthanne) cationique comprenant a) au moins un polyétherol, comme constituant A, b) au moins un diol contenant de l'ammonium ou de l'amine tertiaire, comme constituant B, c) au moins un diisocyanate comme constituant C et d) éventuellement au moins un agent d'arrêt, comme constituant D, ledit poly(éther-uréthanne) cationique présentant un indice d'amide de 5 à 40. Cette invention concerne également un procédé de production de poly(éther-uréthannes) cationiques selon l'invention, des compositions contenant ces poly(éther-uréthannes) cationiques et au moins un tensioactif anionique, un procédé de régularisation de mousse, en particulier pour supprimer la mousse ou pour le démoussage à l'aide d'au moins un poly(éther-uréthanne) cationique selon l'invention et l'utilisation dudit poly(éther-uréthanne) cationique pour régulariser la mousse, en particulier comme agent suppresseur de mousse ou antimousse.
