Abstract
The invention relates to fluoroacrylic monomers of formula: ##STR1## in which R.sub.f denotes a perfluoroalkyl radical, R is hydrogen or a methyl radical, R' denotes an alkyl or cycloalkyl radical, or --NR'-- denotes a 1, 4-piperazinylene radical, W and Z denote divalent connecting groups, Q is oxygen or sulphur or an --NR'-- group, R' denoting hydrogen an alkyl radical, and A is a C.sub.2 or C.sub.3 alkylene group. The polymers (homo- or copolymers) derived from these monomers may be used for the water-repellency and oil-repellency treatment of various substrates, particularly leather.
