Abstract
Aqueous dispersions of fluorinated polyurethanes obtained by the reaction of an organic diisocyanate with a mixture of diols containing ionizable groups and macroglycols comprising polyols and at least 1% by weight of one or more hydroxy- and/or carboxy-capped fluoropolyethers. Said fluorinated polyurethanes are salified, to transform the ionizable groups into hydrophilic cations and/or anions, and are then dispersed in water to be used in textile coatings.
