Abstract of the Disclosure This invention relates to novel acrylates, meth- acrylates, fumarates. maleates, citraconates, mesaconates, itaconates, and aconitates of the following structure: Image wherein R1, R2 are each CnH2n, wherein n is 1 to 12 and may be straight-chain or branched; R3 is hydrogen or CnH2n. wherein n is 1 to 12 and may be straight-chain or branched; R4, R5 and R6 axe hydrogen, methyl, Image , Image , provided that at least one of R4, R5, and R6 is hydrogen or methyl; Rf is CpF2p+1 or CpF2p+1OCqF2q, wherein 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 these unsaturated esters are particularly useful for treating fabrics to make them oil- and water-repellent.
