Organic fluorine cpds. for oil-proofing fabrics and other surfaces Compounds of formula:- (where R1 is H, or advantageously, F; R2 is H or lower alkyl, partic. CH3; n is integer 7-11 and Y is CO- or SO2-) are applied as oil-repellents, in solution or aqs. emulsion, to wood, lacquers, natural or synthetic fabrics, including wool, silk, polyamide, polyester, polyurethane, polyolefine, polyacrylonitrile but partic. natural or regenerated cellulose. They are prepd. by reacting a vinyl sulphonate or (meth)acrylate of a fluorinated alcohol R1(CF2)n-CH2-O-Y-CR2=CH2 with ethylene imine. |
