  • Patent number: 5691000
    Abstract: Phosphoric monoesters of formula: ##STR1## wherein: L is a divalent organic group; m=1; Y is --F or --CF.sub.3 ; Z.sup.+ is selected from: H.sup.+, M.sup.+ wherein M is an alkali metal, N(R).sub.4.sup.+ wherein the R groups, equal or different from each other, are H or C.sub.1 -C.sub.6 alkyls; R.sub.f is a poly-perfluoroalkyleneoxide chain; are used for surface treatment of cellulosic (for instance wood or paper), metallic (either ferrous or non-ferrous), vitreous (for instance glass or vitrified ceramics) materials, or of cements, marbles, granites, and the like.

  • Patent number: 5602225
    Abstract: A process is described for imparting oil- and water-repellency to textile fibers, skin, leather and the like, wherein a composition comprising a functionalized (per)fluoropolyoxyalkylene with silane groups and a phosphoric monoester derived from a (per)fluoropolyoxyalkylene is applied on said materials. As dispersing agent, an hydrophilic organic solvent (for instance an alcohol), optionally in admixture with water can be used. Limpid, stable and easily dilutable formulations are thus obtained, which are capable of imparting very good properties both of oil- and water-repellency. Such properties keep for a long time also after washing both in water by means of detergents and by dry cleaning with organic solvents.

  • Patent number: 5395657
    Abstract: Oil- and water-repellency is imparted to the surface of a porous ceramic material, in particular of "cotto", by applying a phosphoric monoester having formula: ##STR1## where: L is a divalent organic group; m=1; Y is --F or --CF.sub.3 ;Z.sup.+ is a cation; R.sub.f is a polyperfluoroalkylene oxide chain.
