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.
