Abstract
Abstract Fluoroalkyl containing acrylate and methacrylate monomer derivatives of the formula ##STR1## wherein R f is perfluoroalkyl or omega-hydroperfluoroalkyl; R 1 is -alkylene--R 4 -alkylene) n , where n is 0 to 60, R 4 is independently --O--, --S--, --SO 2 --, --NR 1 --, --SO 2 NR 1 -- or --CONR 1 -- where R 1 is hydrogen or alkyl of up to 6 carbon atoms and each "alkylene" contains up to 12 carbon atoms and is unsubstituted or substituted by hydroxy or halo; X is --O--, --S-- or --NR"-- wherein R" is hydrogen or lower alkyl; R 2 is alkylene of up to 12 carbon atoms; and R 3 is hydrogen or methyl, their preparation and their use in the preparation of hydrophobic and oleophobic finishes are disclosed.
