Abstract A silyl vinyl ether having the formula WHEREIN X is an alkylene group of two to 10 carbon atoms, or an alkyleneoxyalkylene group of four to 16 carbon atoms, R is an alkyl group of one to six carbon atoms, y is 0, 1 or 2, and R'' is an alkyl group of 1 to 6 carbon atoms; silyl fluoroolefin polymers made by polymerizing the silyl vinyl ether with fluoroolefins, and, optionally, with other vinyl ethers and/or ethylene and/or propylene and/or fluorine-substituted vinyl ether; compositions containing polysilicic acid and silyl fluoroolefin polymer made by polymerizing the silyl vinyl ether with fluoroolefin, and, optionally, with other vinyl ethers; coating compositions containing a compatible solvent and the polysilicic acid/silyl fluoroolefin polymer composition; articles coated with the silyl-fluoroolefin polymer/polysilicic acid composition and a process for coating them; and polymers made by polymerizing the silyl vinyl ether with formaldehyde or trioxane and, optionally, with alkylene oxides and/or dioxolane and/or alkyl vinyl ethers.
