perfluoroalkyl groups, groups derived from urethanes containing apiclorhidrina and dialcohols radicals, process for its manufacture and its application.

摘要

NEW URETHANES containing at least one perfluoroalkyl group GROUPS AND ALSO REMAINS epichlorohydrin and dialcohols in the molecule. Obtained by reacting a fluorine-containing alcohol with epichlorohydrin TO GIVE adduct perfluoroalkyl epichlorohydrin-ISOCYANATE, AND REACTION OF THIS adduct with a dialcohol or a dialcohol etherified TO GIVE THE DESIRED Urethane a perfluoroalkyl group and with groups epichlorohydrin REMAINS dialcohols, AND REACCIONDE a urethane compound WITH DI-O triisocyanate containing perfluoroalkyl group DESIRED TO GIVE THE VARIOUS perfluoroalkyl urethane groups and EPICLORHIDRINO GROUPS AND REMAINS DIALEOHOLES. NEW urethanes apply to the treatment oleophobic and hydrophobic OF TEXTILES.
