FLUORINATED ACRYLIC MONOMERS, THEIR POLYMERS AND THEIR USE AS HYDROPHOBIC AND OLEOPHOBIC AGENTS

摘要

1. Fluorine-containing acrylic monomers characterized in that they correspond to the general formula : (II) see diagramm : EP0225826,P20,F1 in which RF denotes a perfluoroalkyl radical with a straight or branched chain containing from 2 to 20 carbon atoms, R denotes a hydrogen atom or a methyl radical, A denotes a divalent chain sequence of 2 to 9 carbon atoms, which may comprise one or more oxygen atoms, W-Q denotes a divalent chain sequence chosen from those of formulae : -(CH2 )p -O- see diagramm : EP0225826,P20,F2 see diagramm : EP0225826,P20,F3 -(CH2 )p -O-(CH2 )q -O- -(CH2 )p -S-(CH2 )q -O- -(CH2 )p -(OCH2 CH2 )q -O- -(CH2 )p -SO2 -(CH2 )q -O- see diagramm : EP0225826,P20,F4 see diagramm : EP0225826,P20,F5 -CH=CH-(CH2 )p -O- -(CH2 )p S- -(CH2 )p NH- see diagramm : EP0225826,P20,F6 see diagramm : EP0225826,P20,F7 R' denotes a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms, each of p and q, which are identical or different, denotes an integer ranging from 1 to 20.
