Abstract
Fluorochemical biurets containing one or more monovalent fluoroaliphatic radicals having at least three fully fluorinated terminal carbon atoms and one or more biuret moieties, the radicals and moieties bonded together by hetero atom-containing or organic linking groups are provided. These fluorochemical biurets are useful in the form of aqueous dispersions or emulsions or organic solutions in the treatment of fibrous substrates, such as textile fibers, to impart oil and water repellency.
