PURPOSE:To provide a water and oil repellent having excellent resistance to dry soil as well as excellent oil stain dropping off properties, which comprises a (co)polymer comprising a specific polymerizable monomer and optionally other polymerizable monomer. CONSTITUTION:A polymerizable monomer of the formula (wherein Rf is a group containing a perfluoroalkyl or perfluoroalkylene glycol group; R is an alkylene group; R' is H or methyl; and n is an integer) in such an amount that 10mol% or more polymerizable monomer is copolymerized is polymerized, if necessary, with other polymerizable monomer (e.g.: vinyl halide) in an amount sufficient to copolymerize 0.1-30wt% polymerizable monomer having an ionic group (anionic) in a solvent (e.g.: methyl ethyl ketone) or in an aq. medium in the presence of a emulsifier using a polymerization catalyst.
