Abstract
Abstract A fluorine-containing copolymer comprising (a) 40 to 90 % by weight of repeating units derived from a polymerizable compound having a C4-C20 perfluoroalkyl group, (b) 5 to 50 % by weight of repeating units derived from at least one unsaturated ester selected from the group consisting of stearyl acrylate and stearyl methacrylate, (c) 5 to 50 % by weight of repeating units derived from at least one monomer selected from the group consisting of alkyl acrylate and alkyl methacrylate having 2 to 8 carbon atoms in the alkyl group, which is useful as an active component of a water- and oil-repellent.
