Abstract: The prodn. of aq. polymer dispersions (I) comprises the prodn. of an aq. dispersion of a copolymer (I') of at least two different unsatd. monomers which contains up to 1 wt.% residual unsatd. monomer(s), followed by redn. of this residual monomer content by the action of a redox initiator system contg. an oxidising agent (II) and, as reducing agent (III), the bisulphite adduct of a 3-8C ketone and/or the conjugated acid of this adduct. Also claimed are dispersions (I) of acrylic acid copolymers contg. less than 100 mg free acrylic acid per kg aq. dispersion.
