Abstract: Heteroatom containing perfluoroalkyl terminated oxetanes of the formula ##STR1## the formula ##STR2## are prepared from 3,3-dihalogenated oxetanes and thiols of the formula R.sub.f -E-SH, amines of the formula R.sub.f -E-NH-R, alcohols of the formula R.sub.f -E-OH or perfluoro-amides, wherein R.sub.f is a straight chain perfluoroalkyl of 1 to 18 carbon atoms.The reaction products of these fluorinated oxetanes with nucleophiles are disclosed, as are certain functional derivatives. These products may serve as intermediates or have utility in their own right. Fluorinated polyethers derived therefrom are disclosed and include random or block compositions containing the residue from at least one R.sub.f oxetane, containing two perfluoroalkyl hetero groups.These polyethers provide improved thermal stability and useful low surface energy oil and water repellent coatings for textiles, glass, paper, leather and other materials.
