A polymer comprising polymeric units derived from an acrylate or methacrylate containing a polyfluoroalkyl group, polymeric units derived from an acrylate or methacrylate containing a blocked isocyanate group, and polymeric units derived from an acrylate or methacrylate containing a polyoxyalkylene chain.

Antifouling agent

An aqueous dispersion type stain-proofing agent comprising an aqueous medium and fine particles containing a reaction product (A) and an addition polymer (B), wherein the reaction product (A) is a reaction product of a compound (a.sup.1) having a polyfluoroalkyl group and a group containing active hydrogen reactive with an isocyanate group, with a polyfunctional isocyanate compound (a.sup.2).

Aqueous dispersion type stain-proofing agent and method for its

A water and oil repellant comprising, as effective component, polymer particles each containing at least two polymers, wherein at least one of said at least two polymers is a polymer containing a polyfluoroalkyl group.

Water and oil repellant

A high performance water and oil repellant composed of a compound comprising at least two terminal segments and an intermediate segment connecting the terminal segments and having a molecular weight of from 800 to 20,000, each terminal segment containing at least one polyfluoroalkyl group connected by a --CONH-- linking group, said intermediate segment being a urethane oligomer containing at least two --CONH-- linking groups in one molecule, and said terminal segments and intermediate segment being connected by a --CONH-- linking group.
