ABSTRACT:
The novel urethanes, in addition to at least one perfluoroalkyl group, also contain epichlorohydrin groups and dialcohol radicals in the molecule. They are prepared by reacting a fluorine-containing alcohol with epichlorohydrin to give the perfluoroalkyl-epichlorohydrin adduct, reacting this adduct with a di- or triisocyanate to give the perfluoroalkyl-epichlorohydrin-isocyanate adduct and by reacting this adduct with a dialcohol or a monoetherified dialcohol to give the desired urethanes having a perfluoroalkyl group and having epichlorohydrin groups and dialcohol radicals, and by reacting a suitable urethane compound of this type with a perfluoroalkyl-containing di- or triisocyanate to give the desired urethanes having a plurality of perfluoroalkyl groups and having epichlorohydrin groups and dialcoholradicals. The novel urethanes are preferably used for the oleophobic and hydrophobic finishing of textiles.
