Abstract: To provide a treated polymer production method which can be performed in a simplified manner and at low cost. In order to achieve the object, the treated polymer production method according to the present invention includes: reacting a surface of a polymer with a halogen oxide radical to surface-treat the polymer. The treated polymer is a metal-plated polymer, and the method further includes plating, with a metal, the surface of the polymer after the surface-treating, or the treated polymer is an adhesion laminate of the polymer and an adherend, and the method further includes adhering the adherend to the surface of the polymer after the surface-treating.

Abstract: A water- and oil-repellent composition including a copolymer having a repeating unit derived from a hydrophobic monomer having an ethylenically unsaturated double bond and a hydrocarbon group having from 3 to 40 carbon atoms, and a repeating unit that is derived from a cyclic vinylidene monomer, which is a compound represented by formula (wherein X represents an aliphatic group having from 1 to 10 carbon atoms; and Z represents at least one atom or group that is selected from a hydrogen atom, a hydrocarbon group having from 1 to 6 carbon atoms, and halogen atoms). Also disclosed is method for producing the water- and oil-repellent composition; as well as a textile product to which the copolymer in the water- and oil-repellent composition is attached.
