Abstract: The aqueous solvent-free dispersions contain polymers of monomers of the formulae (1) and (2> H2C=CR-COOC2H4-CnF2n+1 (1), in which R denotes fluorine, chlorine, hydrogen or methyl and n denotes numbers from 5 to 18 H2C=CRX (2), in which R denotes hydrogen or methyl and X denotes a group of the formulae C6H5, CO2CH2C6H5, CO2C2H4C6H5, CN, CO2CH2C6H4Cl, CO2C6H4-C1-C4-alkyl, CO2C2H2n+1 where n = 10 to 22, CONHY, in which Y denotes hydrogen, C1-C4-alkyl, C1-C4-hydroxyalkyl, C1-C4-alkoxy- C1-C4-alkyl or CO2-C1-C20-alkyl, and one or more emulsifiers of the formula (3> CnF2n+1CR R -CHR -(CH2)x-NR2O (3), in which R denotes C1-C4-alkyl or hydroxyethyl, R and R are identical or different and denote C1-C4-alkyl, hydrogen or fluorine, R denotes hydrogen or C1-C4-alkyl, x = 1,2 or 3 and n denotes numbers from 3 to 9, and/or of the formula (4> R R R NO (4), in which R and R may be identical or different and denote C1-C4-alkyl or hydrogen and R denotes C8-C18-alkyl. The dispersions are used as water repellents and oleophobic agents for textiles.
