ABSTRACT:
Stable water-in-oil emulsions of a hydrolyzed polymer of an N-vinylamide of the formula ##STR1## where R and R.sup.1 are each H or C.sub.1 -C.sub.6 -alkyl, are prepared by polymerizing a compound of the formula I, alone or as a mixture with other monoethylenically unsaturated monomers, in the form of a water-in-oil emulsion to give a water-in-oil polymer emulsion, and then hydrolyzing the polymer, hydrolysis of the polymer in the form of the water-in-oil polymer emulsion being carried out in the presence of an acid or base, and additives in the form of antioxidants, reducing agents or aldehyde acceptors being added for stabilization.
