ABSTRACT:
Water-soluble or water-dispersible graft polymers which comprise (a) as main chain, a polyalkylene glycol, in particular polyethylene glycol, which is esterified at the two terminal hydroxyl groups with a long chain fatty acid of 8 to 26, preferably 10 to 22, carbon atoms, and (b) grafted ethylenically unsaturated monomers, preferably acrylic acid or acrylamide, in the form of side chains at individual carbon atoms of the polyalkylene glycol chain.
These graft polymers are particularly suitable for use as anticrease agents for dyeing, whitening, bleaching or washing textile materials, e.g. textiles containing cellulosic fibres, natural or synthetic polyamide fibres, polyacrylonitrile fibres or, in particular, for dyeing or whitening cotton or polyester fibres.
