ABSTRACT:
This invention relates to fluorinated vinyl ethers having the formula ##STR1## wherein t has a value of from 1 to 22; R' is C.sub.2 to C.sub.20 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 ##STR2## 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 ##STR3## where each of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is independently hydrogen or ##STR4## 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.
