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 emulsion polymerization of olefinically saturated monomers comprises heating the reaction mixture by the addition of heated water or steam. A process to reduce the wall coating and coagulate formation during the radically initiated polymerization of olefinically unsaturated monomers in aqueous emulsions at a polymerization temperature of 35-120 deg C comprises heating the reaction mixture to at least the polymerization temperature by the addition of heated water and/or steam.

Abstract: A process is described for effectively reducing the residual monomer content of an aqueous polymer dispersion by aftertreatment at atmospheric pressure or above with an initiator system comprising a) a hydroperoxide, hydrogen peroxide or a peracid, and b) an alpha-hydroxy carboxylic acid, such as tartaric acid, or with a salt thereof.
