Abstract
Process for preparing a water- and oil-repelling agent composition, which is obtained by solution-polymerizing a polymerizable monomer component which contains at least a monomer having a polyfluoroalkyl group in a polymerization solvent which contains at least one compound with a boiling point of 0.degree. to 150.degree. C. selected from the group consisting of a hydrochlorofluorocarbon having 2 to 3 carbon atoms and a hydrofluorocarbon having 4 to 6 carbon atoms and 4 or more fluorine atoms, said solvent containing the compound in an amount of at least 5% by weight, and the water- and oil-repelling agent composition prepared thereby.
