Abstract

Abstract Translated from German Die beschriebenen Urethane sind aufgebaut aus aliphatischem Fluoralkohol, Triisocyanat und einer Carbonsäure. Sie werden hergestellt durch Reaktion des aliphatischen Fluoralkohols mit dem Triisocyanat zum Fluoralkohol-Triisocyanat-Addukt und durch Reaktion dieses Adduktes mit der Carbonsäure. Die neuen Urethane werden vorzugsweise zur Ausrüstung von Textilien in der Wasser-, öl- und Schmutzabweisung verwendet. The urethanes described are made up of aliphatic fluoroalcohol, triisocyanate and a carboxylic acid. They are produced by reacting the aliphatic fluoroalcohol with the triisocyanate to form the fluoroalcohol-triisocyanate adduct and by reacting this adduct with the carboxylic acid. The new urethanes are preferably used for finishing textiles in water, oil and dirt repellency.
