Definitions

  • the object of the present invention is to provide other graying inhibitors for detergents and graying inhibitors for the aftertreatment of textile goods containing synthetic fibers.
  • the polyalkylene oxides of molecular weight (number average) from 300 to 100,000 based on ethylene oxide, propylene oxide and / or butylene oxide given under a) above serve as the graft base.
  • Homopolymers of ethylene oxide or copolymers having an ethylene oxide content of 40 to 99 mol% are preferably used.
  • the proportion of ethylene oxide polymerized in is therefore 40 to 100 mol% for the ethylene oxide polymers to be used with preference.
  • Propylene oxide, butylene oxide and / or isobutylene oxide are suitable as comonomers for these copolymers.
  • copolymers of ethylene oxide and propylene oxide for example, copolymers of ethylene oxide and propylene oxide, copolymers of ethylene oxide and butylene oxide and copolymers of ethylene oxide, propylene oxide and at least one butylene oxide are suitable.

Of the monomers of group (c), vinyl acetate, vinyl propionate, methyl acrylate or mixtures of vinyl acetate and methyl acrylate are preferably used.
  • the polyalkylene oxides of component (a) which are considered are grafted with the monomers of component (b) in the presence of initiators which form free radicals or by the action of high-energy radiation, which should also be understood to mean the action of high-energy electrons.
  • This can be done by dissolving the polyalkylene oxide in at least one monomer of group (b) and polymerizing the mixture after adding a polymerization initiator.
  • the graft polymerization can also be carried out semi-continuously by initially introducing a portion, for example 10%, of the mixture of polyalkylene oxide to be polymerized, at least one monomer from group (b) and / or (c) and initiator, heating to the polymerization temperature and after the light-off Polymerization adds the rest of the mixture to be polymerized as the polymerization progresses.

  • the polyalkylene oxides are solid substances at room temperature up to temperatures of 50 ° C. to 60 ° C. and are readily soluble or dispersible in water. These are linear or branched reaction products of ethylene oxide with propylene oxide and / or isobutylene oxide, which have a block structure or which can also have a statistical structure.
  • the end groups of the polyalkylene oxides can optionally be closed. This should be understood to mean that the free OH groups of the polyalkylene oxides can be etherified and / or esterified and / or aminated and / or reacted with isocyanates.

  • the amounts used are 0.01 to 0.3 g / l wash liquor.
  • the use of the graft polymers in the last rinsing bath of a washing machine cycle has the advantage that the laundry is soiled much less by detached dirt particles which are present in the washing liquor during the next washing cycle than without the addition of the graying inhibitor in the previous washing.
