| 摘要 |
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 t o the use of said cationic poly(ether-urethane) for foam regulation, especiall y as a foam suppressing agent or a defoaming agent.
