O.Z. 0050/41788 Abstract of the Disclosure: Aqueous polymer dispersions are obtainable by polymerizing a monomer mixture which contains from 10 to 100 % by weight of halogenated monomers by radical emulsion polymerization in aqueous medium, adjusting the pH of the aqueous phase of the resulting aqueous polymer dispersion to from 5 to 10 by addition of bases which differ from ammonia and from primary and secondary amines, and adding from 0.005 to 1 % of the weight of the monomer mixture of one or more substances from the group comprising glycerol, pivalic acid, paraldehyde, 2,6-di-tert-butyl-p-cresol, benzo- phenone, alkyl-substituted benzophenones, thiosulfuric acid and salts thereof, and oxalic acid and salts there- of, it being possible to add both the bases and the one or more substances before, during and/or after the emulsion polymerization.
