Abstract

Process for preparing polymers which are water-soluble or water-dispersible or which, if consisting of monomers with neutralizable radicals, are soluble in water or dispersible in water in neutralized form, by subjecting(a) ethylenically unsaturated monomers to free-radical polymerization in the presence of(b) polyalkylene oxide-containing silicone derivatives.
