Abstract
Novel fluorinated, acrylamide monomers are prepared from 2-alkenyl azlactones reacted with fluorinated alcohols. The novel monomers have the formula ##STR1## wherein R.sup.1 and R.sup.6 are independently hydrogen or methyl; PA0 R.sup.2 and R.sup.3 independently can be an alkyl, cycloalkyl, or aryl group, or R.sup.2 and R.sup.3 taken together with the carbon to which they are joined can form a carbocyclic ring containing 4 to 12 ring atoms; PA0 R.sup.4 and R.sup.5 are independently hydrogen or lower alkyl; PA0 a is 0 or 1; PA0 b is 1 or 2; PA0 X is a single bond, CH.sub.2, CH.sub.2 OCH.sub.2, and CH.sub.2 CH.sub.2 OCH.sub.2 ; and PA0 R.sub.F is a substantially perfluorinated alkyl, cycloalkyl, or aryl group when b is 1 and perfluorinated alkylene when b is 2. Novel polymers and copolymers can be prepared from the monomers of the invention.
