    • 23189-6646 Polyether siloxane graft polymers Novel graft copolymer comprising a) 0.1 to 99.9% by weight of polyalkylene oxide-organo-polysiloxane block and/or comb polymer units and b) 99.1 to 0.1% by weight of units of polymerized perfluoroalkyl substituted allyl compounds, which graft polymers contain structural elements corresponding to the following general formula: wherein X denotes a hydrogen atom or a methyl group, Y and Z denote, independently of one another, a hydrogen atom or an alkyl group containing 1 to 18 carbon atoms Q denotes a divalent alkylene group with 1 to 12 carbon atoms or other divalent radicals, Rf denotes a perfluorinated aliphatic, optionally branched group with 1 to 20 carbon atoms and the group may contain at most one hydrogen or chlorine atom on two carbon atoms in addition to the fluorine atoms, RSi denotes a polyalkylene oxide-organopolysiloxane block and/or comb polymer residue and Rpo denotes a polyalkylene oxide chain of the polyalkylene oxide-organopolysiloxane block and/or comb polymer, and in the graft polymers, more than 50% by weight of perfluoroalkyl substituted allyl monomers have been added in monomolecular form
