ABSTRACT:
Aqueous polymer dispersions are obtainable by polymerizing a monomer mixture which contains from 10 to 100% by weight of halogenated monomers in the presence of from 0.5 to 6% by weight, based on the monomer mixture, of exclusively anionic and/or non-ionic emulsifiers by radical emulsion polymerization in aqueous medium, and adjusting the pH of the aqueous phase of the resulting aqueous polymer dispersion to from 5 to 10 by addition of bases which are different from ammonia and from primary and secondary amines, it being possible for the bases to be added before, during and/or after the emulsion polymerization.
