Fluoropolymer of fluorinated short chain acrylates or methacrylates and oil-and water repellent compositions based thereon |
摘要 |
The present invention relates to compositions based on a fluoropolymer comprising repeating units derived from (i) one or more fluorinated monomers selected from the group consisting of monomers according to the general formula: Rf-X-OC(O)-C(R)=CH2 wherein Rf represents a perfluorinated aliphatic group having 3 or 4 carbon atoms, X is an organic divalent linking group and R represents hydrogen or a lower alkyl group having 1 to 4 carbon atoms; and (ii) one or more non-fluorinated comonomers. The fluoropolymer has a weight average molecular weight between 3000 and 55000. The compositions may be solvent born or aqueous born and are particularly useful to provide good oil- and/or water repellency properties to the substrate.
