1-18555/A/CGC 1535 HETEROATOM CONTAINING PERFLUOROALKYL TERMINATED NEOPENTYL MERCAPTO-ALCOHOLS AND COMPOSITIONS THEREFROM Abstract of the Disclosure Heteroatom containing perfluoroalkyl terminated neopentyl mercapto-alcohols of the formulas I and 11 HS-[CH2C(CH2X-E-Rf)2CH2]-OH (I) Hs-[CH2C(CH2X1-Rf)2CH2]-OH (II) are prepared from the corresponding perfluorinated neopentyl oxetanes where Rf is a straight or branched chain perfluoroalkyl of 1 to 18 carbon atoms or said perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms, E is a linking group, and X and X1 are heteroatom moieties. The reaction products of these fluorinated mercapto-alcohols with electrophiles are disclosed as are certain functional derivatives. Compositions containing such materials provide improved thermal stability and useful low surface energy oil and water repellent coatings for textiles, glass, paper, leather, and other materials.
