Abstract: The invention relates to glass-clear, thermoplastic moulding compositions comprising (A) a polymer of vinyl chloride, (B) a copolymer made from (b1) a methylstyrene and (b2) acrylonitrile, and (C) optionally assistants and additives, characterised in that the moulding compositions contain, as component (B), a copolymer which contains, as the methylstyrene (b1), p-methylstyrene copolymerised in a certain amount. The result is moulding compositions having good heat distortion resistance and excellent optical transparency.
