摘要： 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.

摘要： An oil repellent agent including a modified natural product having at least one hydroxyl group, wherein a hydrogen atom of the hydroxyl group is replaced with an R group represented by —Y—Z, wherein Y represents a direct bond, —C(═O)—, —C(═O)—NR′— or —C(═S)—NR′—, where R′ represents a hydrogen atom or a C1 to C4 alkyl group); and Z represents a hydrocarbon group having 1 to 40 carbon atoms and optionally having a substituent or a polysiloxane. The natural material is a natural product other than starch and preferably is a monosaccharide, a polysaccharide, glycerin or polyglycerin. Also disclosed is a textile product to which the oil-resistant agent is attached, an oil-resistant paper and a method of treating paper with the oil-resistant agent.
