Abstract: A method is claimed for using cationically stabilised aq. polymer dispersions (PD) as binders for moulded prods. based on finely divided materials with a negative surface charge (M). These dispersions contain (A) a dispersed copolymer (A) with a static Tg of 40-110 deg. C, based on (a) 30-80 pts. wt. styrene, (b) 20-70 pts. wt. (1-8C alkyl) (meth)acrylate(s) and (c) 0-10 pts. wt. other radically copolymerisable monomers, and (B) as dispersant, a mixt. of prim., sec. and/or tert. organic mono-amine(s) with at least 8 C atoms and acid addn. salts thereof. Also claimed are (i) polymer dispersions (PD) as above; (ii) moulded prods. based on materials (M) and binders (PD); (iii) rectangular moulded sheets based on (M) and (PD), with a length and breadth of 30-70 cm and a thickness of 1-20 mm; (iv) a process for the prodn. of mouldings (ii), by suspending material (M) in water, adding dispersion (PD), precipitating copolymer (A) onto material (M) by adding bases or salts of multivalent anions, placing the mixt. obtd. in a mould, removing water, and drying; (v) moulded prods. obtd. by this process.

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: 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 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.
