Abstract
Lubricant-containing aqueous preparations of copolymers are obtainable by polymerisation of PA1 (A) 70 to 95% by weight of a monomer mixture of PA2 (a) 20 to 90% by weight of an ethylenically unsaturated carboxylic acid, in particular of a monocarboxylic acid, or of a corresponding amide, PA2 (b) 10 to 80% by weight of a sulfonated, aliphatic or aromatic monovinyl compound, and PA2 (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 PA1 (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,
