Abstract: The invention relates to glass-clear thermoplastic moulding compositions comprising (A) a polymer of vinyl chloride, (B) a copolymer of (b1) a methylstyrene and (b2) a nitrile, and (C) optionally auxiliaries and additives, characterised in that the moulding composition contains, as component (B), a copolymer which contains as methylstyrene (b1) p-methylstyrene and as nitrile (b2) methacrylonitrile - in a certain ratio - in copolymerised form. The products are moulding compositions having good heat distortion resistance (heat resistance) and excellent transparency to light.

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: Thermal cleaning of articles that come into contact with polymer dispersions comprises treatment in a sand fluidised bed at a temperature high enough to pyrolyse and/or vaporise the contaminants produced by the polymer dispersions. Also claimed is the use of a sand fluidised bed for cleaning these articles.

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.
