ABSTRACT:
Water-soluble or water-dispersible graft polymers comprising i) as main chain, (1) a condensate of (A) (1) an aliphatic monoalcohol of 6 to 22 carbon atoms or (2) a fatty acid of 8 to 22 carbon atoms with (B) the reaction product of (a) an adduct of propylene adduct with at least trihydric aliphatic alcohol of 3 to 10 carbon atoms, (b) an aliphatic dicarboxylic acid of 4 to 10 carbon atoms, or an anhydride thereof, and (c) an aliphatic diol having an average molecular weight of not more than 1800 and ii) grafted ethylenically unsaturated polymerisable monomers, preferably acrylic acid or acrylamide, in the form of side chains at individual carbon atoms of said condensate.
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.
