Heteroatom containing perfluoroalkyl terminated neopentyl glycols of the formulas HO[CH2C(CH2X-E-Rf)2CH2O]1-3-H or HO[-CH2C(CH2X-Rf)2CH2O]1-3-H are prepared from halogenated neopentyl glycols or oxetanes and thiols of the formula Rf-E-SH, amines of the formula Rf-E-NH-R, alcohols of the formula Rf-E-OH or perfluoro-amides, wherein 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. 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 Rf-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.
