Abstract: Polyurethanes and polyesters are described which are the reaction products of an aromatic, aliphatic or cycloaliphatic diisocyanate, or of a diacid or diacid derivative respectively, with a diol containing a pendent UV-absorbing moiety, optionally also with one or more other diols or diamines. These UV-absorbing polycondensates can be applied to the surfaces of substrates by exhaustion methods or by spraying and act to protect polymers and dyes from degradation by UV radiation. They are therefore useful, either alone or in combination with other coating materials, for the treatment of wood, paper, textiles, leather or other surfaces which are exposed to degrading radiation.

Abstract: The instant invention relates to polysiloxane polyoxyalkylene compounds containing at least one perfluoroalkyl terminated polyoxyalkylene group. These compounds are useful as surfactants and improve or impart properties such as wetting, penetration, spreading, levelling, foam stability, flow properties, dispersion properties and oil and water repellency.

Abstract: Tris-perfluoroalkyl terminated neopentyl alcohols of the formula (R.sub.f --E.sub.n --X--CH.sub.2).sub.3 CCH.sub.2 OH prepared from halogenated neopentyl alcohols and thiols of the formula R.sub.f --E.sub.n --SH, amines of the formula R.sub.f --E.sub.n --NH--R, alcohols of the formula R.sub.f --E.sub.n --OH, perfluoro-acids or amides, are described. The alcohols react with isocyanates to prepare urethanes; with acids or derivatives, to prepare esters or carbonates; with epoxides to form ethers. Further, they may be converted to halide intermediates. The products all contain the residue of at least one R.sub.f -neopentyl alcohol containing three perfluoroalkyl hetero groups.

Abstract: This invention relates to polymeric compositions derived by the polycondensation of heteroatom containing perfluoroalkyl terminated neopentyl glycols, and diamino, dihydroxy, or dimercapto-polysiloxanes and optionally other diols, dimercaptans or diamines with organic diisocyanates; and blends of polycondensation polymers with oxime-blocked organic polyisocyanates. These compositions and blends are useful as coatings on glass, wood, paper, leather and especially textiles.

Abstract: A transportable crude oil in water emulsion which is stable to both breakdown and phase inversion up to at least about 50.degree. C., containing an effective, compatible emulsion stabilizing amount of an anionic, nonionic or amphoteric fluorochemical surfactant, and optionally a hydrocarbon surfactant, and a method of transporting a crude oil in the form of such emulsion.
