Abstract
Abstract This invention relates to novel acrylates, methacrylates, fumarates, maleates, citraconates, mesaconates, itaconates, and aconitates of the following structure: ##STR1## where R 1 , R 2 are each C n H 2 .sbsb.n, where n is 1 to 12 and may be straight chain or branched; R 3 is hydrogen or C n H 2 .sbsb.n+1, where n is 1 to 12 and may be straight chain or branched; R 4 , r 5 and R 6 are hydrogen, methyl, ##STR2## PROVIDED THAT AT LEAST ONE OF R 4 , R 5 , and R 6 is hydrogen or methyl; R f is C p F 2p+1 or C p F 2p+1 OC q F 2q , where p is 3 to 18 (preferably 6 to 12), q is 2 to 8, and the perfluoroalkyl constituent may be branched or straight chain. Addition polymers made from the above unsaturated esters are particularly useful for treating fabrics to make the fabric oil and water repellent.
