Fluoralkane, Fluorchloralkane, fluoralkylsubstituierte Aromaten, Alkylester von Perfluoralkansäuren, chlorierte Alkane oder Aromaten, aromatische Kohlenwasserstoffe, Ketone, Ester und Aether. Besonders zweckmässige Lösungsmittel sind fluorierte Lösungsmittel und insbesondere a,a,a-Trifluortoluol, auch als Benzotrifluorid bekannt, Hexafluorxylol und deren Gemische mit Essigester oder Aceton. Die Konzentrationen der erfindungsgemässen fluorierten Polymeren im Lösungsmittel zur Erzeugung von Ueberzügen mit wirksamen öl- und wasserabstossenden Eigenschaften liegen im allgemeinen im Bereich von 0,01 bis 10% und vorzugsweise 0,1 bis 2,0 Gew.-%. Gemische aus Emulsionen der erfindungsgemässen Polymeren mit vermischten Emulsionen anderer Polymerer und Copolymerer sind besonders zweckmässig für Textilausrüstungen. Die Polymeren und Copolymeren gehören im allgemeinen dem nichtfluorierten Typ an ; wie unten angegeben sind jedoch andere fluorierte Polymere und Copolymere gewünschtenfalls verwendbar. Beispiele für in solchen Gemischen verwendbare nichtfluorierte Polymere sind, ohne darauf beschränkt zu sein, Polymere und Copolymere von Alkylacrylaten und Alkylmethacrylaten, wie Methylmethacrylat, Aethylmethacrylat, Hexylmethacrylat und n-Octylmethacrylat. Poly-n-octylmethacrylat ist als solches Polymer besonders geeignet. Ferner kommen Polymere und Copolymere von Acrylsäure, Methacrylsäure, Styrol, Alkylstyrol, Butadien, 2-Methyl-1,3-butadien, 2-Chlor-1,3-butadien, Polymere und Copolymere von Vinylestern wie Vinylacetat, Vinylbutyrat, Vinyllaurat, Vinylstearat und Vinyl-2-äthylhexanoat, Polymere und Copolymere von Vinylhalogeniden und Vinylidenhalogeniden, wie Vinylchlorid, Vinylidenchlorid, Vinylfluorid und Vinylidenfluorid, Polymere und Copolymere von Allylestern wie Allylpropionat oder Allylcaprylat, Polymere und Copolymere von Vinyläthern wie Methylvinyläther, Cetylvinyläther, sowie Polymere und Copolymere von Acrylamid, Methacrylamid, N-Methylolacrylamid, N-Methylolmethacrylamid, N-Isopropylacrylamid und Methacrylnitril dabei in Frage.Coatings made from the homopolymers and copolymers according to the invention can be prepared as solutions or aqueous emulsions and applied from these. Suitable solvents are, for. B. fluoroalkanes, fluorochloroalkanes, fluoroalkyl-substituted aromatics, alkyl esters of perfluoroalkanoic acids, chlorinated alkanes or aromatics, aromatic hydrocarbons, ketones, esters and ethers. Particularly useful solvents are fluorinated solvents and in particular a, a, a-trifluorotoluene, also known as benzotrifluoride, hexafluoroxylene and their mixtures with ethyl acetate or acetone. The concentrations of the fluorinated polymers according to the invention in the solvent for producing coatings with effective oil- and water-repellent properties are generally in the range from 0.01 to 10% and preferably 0.1 to 2.0% by weight. Mixtures of emulsions of the polymers according to the invention with mixed emulsions of other polymers and copolymers are particularly useful for textile finishes. The polymers and copolymers are generally of the non-fluorinated type; however, as noted below, other fluorinated polymers and copolymers can be used if desired. Examples of non-fluorinated polymers which can be used in such mixtures include, but are not limited to, polymers and copolymers of alkyl acrylates and alkyl methacrylates, such as methyl methacrylate, ethyl methacrylate, hexyl methacrylate and n-octyl methacrylate. Poly-n-octyl methacrylate is particularly suitable as such a polymer. In addition, there are polymers and copolymers of acrylic acid, methacrylic acid, styrene, alkylstyrene, butadiene, 2-methyl-1,3-butadiene, 2-chloro-1,3-butadiene, polymers and copolymers of vinyl esters such as vinyl acetate, vinyl butyrate, vinyl laurate, vinyl stearate and Vinyl-2-ethylhexanoate, polymers and copolymers of vinyl halides and vinylidene halides, such as vinyl chloride, vinylidene chloride, vinyl fluoride and vinylidene fluoride, polymers and copolymers of allyl esters such as allyl propionate or allyl caprylate, polymers and copolymers of vinyl ethers such as methyl vinyl ether, cetyl vinyl ether, and also of acryl amide copolymers Methacrylamide, N-methylolacrylamide, N-methylolmethacrylamide, N-isopropylacrylamide and methacrylonitrile are possible.
Die hier offenbarten Polymeren besitzen wünschenswerte schmutzabweisende Eigenschaften. Die relative Wirksamkeit der Polymeren wird dabei zweckmässig durch Messungen des Kontaktwinkeis eines solchen Polymeren gegenüber Wasser, Methylenjodid und Hexadecan festgestellt.The polymers disclosed here have desirable soil-repellent properties. The relative effectiveness of the polymers is expediently determined by measuring the contact angle of such a polymer with water, methylene iodide and hexadecane.
