Abstract: An aqueous composition comprises a mixture of from 10 to 50% by weight of a polymer A) having a gel content of less than 40% by weight and a number-average molecular weight M n of the soluble fractions of less than 30,000 and from 50 to 90% by weight of a filler B), the amounts by weight being based on the weight sum of the polymer and of the filler.

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.

Abstract: In the production of vinyl-lactam copolymers by free radical polymerization of water-soluble N-vinyl-lactam(s) and hydrophobic comonomer(s) in an organic solvent in the presence of an initiator under reflux conditions, the condensate formed in the reflux is recycled into the polymerization mixture from below.
