    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: Light-weight building panels based on mineral fibres A and thermoplastic binders contain 1 to 25% by weight, relative to A, of a copolymer B having a glass transition temperature from 70 to 105 DEG C and built up essentially from 50 to 98% by weight of methyl methacrylate I, 2 to 50% by weight of one or more acrylates II of C1-C8-alkanols and 0 to 2.5% by weight of one or more crosslinking monomers III as binders, 0 to 150% by weight of fillers C and, relative to B, 0.2 to 15% by weight of one or more amines F of the general formula in which R is C8-C18-alkyl or C8-C18-alkenyl, U and V are C2-C4-alkylene, X and Y are hydrogen, C1-C18-alkyl or C2-C18-alkenyl and n and m are integers from 0 to 10, or acid addition salts thereof.
