  • Patent number: 10844151
    Abstract: An aqueous dispersion free of fluorochemicals comprising (A) at least one copolymer obtained by polymerization of the following monomers a) at least one fluorine-free (meth)acrylate ester of a C16-C18 alcohol, b) at least one fluorine-free (meth)acrylate ester of a C18-C22 alcohol, c) at least one monomer selected from the group of vinyl chloride and vinylidene chloride, and, optionally, d) at least one monomer selected from the group of 2-hydroxyethyl(meth)acrylate and 3-chloro-2-hydroxyethyl(meth)acrylate, (B) at least one component selected from the group of a paraffin wax, (C) at least one surfactant, and (D) water, wherein the monomers a) and b) of copolymer (A) are distinct, and the copolymer (A) does not contain any polymerized units of styrene or ?-methylstyrene, is useful for the finishing of natural and synthetic textile fabrics to endow the said fabrics with excellent water repellent properties.

  • Patent number: 8568875
    Abstract: Copolymers which are composed of at least 4 monomers, including (meth)acrylate compounds containing perfluoroalkyl groups, are suitable for the treatment of fiber materials. The copolymers are usually used here in the form of aqueous dispersions. The fiber materials are in particular fabrics, for example made of polyolefin. Treatment with the copolymers imparts to them oil- and water-repellent properties and also repellent properties toward low molecular weight alcohols.
