Abstract: A process is described for reducing the residual monomer content in a liquid solution, mixture, melt, suspension or dispersion of a polymer by postpolymerization with addition of a redox initiator system at a reaction temperature appropriate to it and with an extremely short mixing time of the liquid system in the production reactor by metering-gradually, in portions or continuously-at least one of the redox initiator components required to initiate polymerization of the residual monomers over a period (metering time) which is from about 10 to 250 times the mixing time of the liquid system in said reactor.

Abstract: The invention relates to an aqueous polymer dispersion which may optionally contain mineral additives and/or pigments and which essentially consists of a mixture of A) a 20% to 65% w/w aqueous dispersion of a copolymer of (a) an olefinically unsaturated compound containing one or more carboxyl groups and/or amide groups, and (b) at least two monomers selected from the group consisting of acrylates and methacrylates and vinylaromatic compounds, and B) from 0.1 to 5% w/w, based on the weight of the copolymer contained in component (A), of at least one aromatic ketone of the general formula (I) aryl radical and R1 stands for an aryl radical containing from 1 to 3 radicals of the formula -O-C(O)-O- attached to one or more oxaalkylene groups. Such polymer dispersions are suitable for the manufacture of paints and coating systems.
