FLUORIERTE ACRYLMONOMERE, IHRE POLYMERE UND IHRE ANWENDUNG UM VERSCHIEDENE SUBSTRATE WASSER- UND OELABWEISEND ZU MACHEN.

摘要

The invention relates to fluoroacrylic monomers of formula: in which Rf 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 C2 or C3 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.
