Compositions of matter including the structural unit ##EQU1## wherein R.sub. F ' is a divalent polyfluoroalkylene group having a chain length of from 1 to 4 carbon atoms which may be substituted at one or more positions with chloro-or polyfluoroalkyl, chlorofluoroalkyl or polyfluorocycloalkyl groups containing up to six carbon atoms; and R.sub.F is a monovalent straight or branched chain, or cyclic, polyfluoroalkyl group or a chlorofluoroalkyl group containing up to ten carbon atoms and the R.sub.F groups are the same or different or is a divalent polyfluoroalkylene group having a chain length of from 1 to 4 carbon atoms which may be substituted at one or more positions with chloro or polyfluoroalkyl, chlorofluoroalkyl or polyfluorocycloalkyl groups containing up to six carbon atoms and the R.sub.F groups are interconnected to form a cyclic structure.
