  • Fluorine-free aqueous dispersions for the finishing of textile fabrics
    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.
