This invention relates to fluorinated vinyl ethers having the formula <IMAGE> wherein t has a value of from 1 to 22; R' is C2 to C20 alkylene, alkoxyalkylene, arylene or aryloxyalkylene which radicals are optionally fluorinated; R'' is a divalent radical having from 1 to 100 carbon atoms and is selected from the group of alkylene, arylene, alkarylene, aralkylene which groups are optionally substituted with lower alkyl or the radical <IMAGE> +TR <IMAGE> wherein R is a polyvalent linear, branched or cyclic hydrocarbon radical having from 2 to 20 carbon atoms, optionally substituted with alkyleneoxy; A is a divalent radical selected from the group of <IMAGE> where each of R1, R2, R3 and R4 is independently hydrogen or <IMAGE> B is lower alkyl; m has a value of from 0 to 4 and n has a value of from 0 to 20. The invention also relates to the manner of synthesizing the present fluorinated vinyl ethers and to their uses as release agents and stain protective coatings.
