Fluorinated acrylic monomers as hydrophobic and oleophobic agents

摘要

The invention relates to fluorinated acrylic monomers of the formula: in which A and W denote divalent linkages, R is a hydrogen atom or a methyl radical, RF is a perfluoroalkyl radical and Q denotes an oxygen or sulphur atom or the group-NR'-, where R' denotes a hydrogen atom or an alkyl radical. Homo- or copolymers derived from these monomers are useful for the water or oil-repellent treatment of various substrates, particularly leather.
