1-17256/+ Graft polymers which are water-soluble or dispersible in water, their preparation and use Graft polymers which are obtainable from (A) 2 - 30 % by weight of an addition product from alkylene oxide onto an aliphatic alcohol which is at least trihydric having 3 to 10 carbon atoms and (B) 70 - 98 % by weight of a grafted-on monomer mixture of (1) 20 to 50 % by weight of an N-substituted or N-unsubstituted acrylamide or methacrylamide and (2) 50 to 80 % by weight of an N-vinyl-substituted amide or of a vinyl ester, derived in each case from a saturated aliphatic monocarboxylic acid, where the sums of (A) and (B), and (1) and (2) in each case add up to 100 %. These novel graft polymers are suitable as dyeing assistants, particularly as padding assistants or liquor binders when dyeing cellulose fibre materials. |
