Fluorinated polymers derived from acrylamide-functional monomers

摘要

Novel fluorinated, acrylamide monomers are prepared from 2-alkenyl azlactones reacted with fluorinated alcohols. The novel monomers have the formula <IMAGE> III wherein R1 and R6 are independently hydrogen or methyl; R2 and R3 independently can be an alkyl, cycloalkyl, or aryl group, or R2 and R3 taken together with the carbon to which they are joined can form a carbocyclic ring containing 4 to 12 ring atoms; R4 and R5 are independently hydrogen or lower alkyl; a is 0 or 1; b is 1 or 2; X is a single bond, CH2, CH2OCH2, and CH2CH2OCH2; and RF 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.
