Lubricant-containing aqueous preparations of copolymers are obtainable by polymerisation of (A) 70 to 95 % by weight of a monomer mixture of (a) 20 to 90 % by weight of an ethylenically unsaturated carboxylic acid, in particular of a monocarboxylic acid, or of a corresponding amide, (b) 10 to 80 % by weight of a sulfonated, aliphatic or aromatic monovinyl compound, and (c) 0 to 25 % by weight of N-vinylpyrrolidone or of an N-vinyl-substituted amide of a saturated aliphatic monocarboxylic acid in the presence of (B) 5 to 30 % by weight of a polyol whose hydroxyl groups have been esterified with a fatty acid of 8 to 26 carbon atoms, the sum totals of (A) and (B) on the one hand and (a), (b) and (c) on the other each adding up to 100 %. The novel preparations are suitable for use as textile auxiliaries, in particular for preventing crease marks in textile wet processing.
