Water-and-oil repellant composition

Providing even be processed at low temperatures can also impart hydrophobic oleophobic products, soft touch and can be reached hydrophobic oleophobic hydrophobic processing oil repellent composition. A copolymer of polymerized units of the hydrophobic and oil repellent agent composition essentially containing the following monomer (a) and following monomer (b) is an essential component for the polymerization units. Monomer (a): R f monomers, homopolymers by the R f group produced a microcrystalline no melting point or a melting point of 50 ℃. Monomer (b): a monomer containing no R f group, its microcrystalline melting point of the homopolymer side chain generated by more than 30 ℃.
