    Abstract: Heteroatom containing perfluoroalkyl terminated neopentyl glycols of the formulas HO[-CH₂C(CH₂X-E-R f )₂CH₂O]₁₋₃-H or HO[-CH₂C(CH₂X-R f )₂CH₂O]₁₋₃-H are prepared from halogenated neopentyl glycols or oxetanes and thiols of the formula R f -E-­SH, amines of the formula R f -E-NH-R, alcohols of the formula R f -E-OH or perfluoro-amides, wherein R f 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.
    The polymeric reaction products of said fluorinated diols, and optionally other diols with isocyanates to prepare polyurethanes; with amines and isocyanates to prepare polyureas/polyurethanes; with acids or derivatives to prepare polyesters or polycarbonates are disclosed. These include polymeric, random or block urethane, and/or urea, and/or ester compositions containing the residue of at least one R f -­neopentyl glycol containing two perfluoroalkyl hetero groups.
    These polymeric compositions provide improved thermal stability and useful low surface energy oil and water repellent coatings, and soil-release properties for textiles, glass, paper, leather and other materials.
