PROCESS FOR SURFACE TREATMENT OF CELLULOSIC, METALLIC, VITREOUS MATERIALS, OR CEMENTS, MARBLES, GRANITES AND THE LIKE

摘要

Phosphoric monoesters of formula:wherein:L is a divalent organic group; m = l; Y is -F or -CF,; Z+ isselected from: H+, M+ wherein M is an alkali metal, N(R),'wherein the R groups, equal or different from each other, areH or C1-C6 alkyls; R f is a poly-perfluoroalkyleneoxide chain;are used for surface treatment of cellulosic (for instancewood or paper), metallic (either ferrous or non-ferrous),vitreous (for instance glass or vitrified ceramics) materials,or of cements, marbles, granites, and the like.
