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: A process for the production of low-viscosity, aqueous polymer dispersions (APD), with polymer concentrations of at least 50 vol% and viscosities of less than 1000 mPa.s, comprises radical emulsion polymerisation of ethylenic monomers (except vinyl and vinylidene halides), by the monomer addition method, in the presence of an initiator and small amounts of water-miscible organic solvent(s) (I). Also claimed are APD obtained by this process.
