Abstract (en)
[origin: US4775488A] An agent effective for oleophobizing and hydrophobizing textiles is an aqueous anionic dispersion which comprises water and (A) 5 to 25% by weight of a reaction product which contains at least one bis-(2-fluoroalkyl-ethoxy-carbonylamino)-toluene of the formula YCF2(CF2)nCH2CH2OCO +TR <IMAGE> wherein n is a number from 5 to 15 and Y is -H or -F, and wherein said reaction product is prepared by reacting 2-perfluoroalkylethanol of the formula YCF2-(CF2)n-CH2CH2OH with tolylene diisocyanate in a molar ratio of (1.8 to 2):1 in the presence of 2 to 5% by weight of N-methylpyrrolidone, relative to the perfluoroalkylethanol, (B) 1 to 14% by weight of at least one emulsifier of the formula YCF2(CF2)p-CH2CH2O-CO-NH-CH2CH2-SSO3X wherein p is a number from 5 to 15, Y is -H or -F, and X is a monovalent cation, (C) 1 to 14% by weight of at least one nonionic emulsifier of the formula YCF2-(CF2)q-CH2CH2-(OCH2CH2)r-OH wherein Y is -H or -F, q is a number from 5 to 15, r is a number from 0 to 10, and (D) 5 to 30% by weight of a solvent or solvent mixture, with the proviso that the sum of the amounts of components (B) and (C) is 2 to 15%.
