Abstract

Thermoplastic moulding compounds obtained from: from 98 to 10 parts, by weight, of aromatic polycarbonates having an average molecular weight M.sub.w (by light scattering) of from 10,000 to 200,000; from 60 to 0 parts, by weight, of polyalkylene terephthalate; from 30 to 0 parts, by weight, of graft polymer of one or more ethylenically unsaturated monomers on a rubber; and from 90 to 2 parts, by weight, of a polyester of terephthalic acid and a diol containing at least one diaryl sulphone group in the molecule and, optionally, an aliphatic diol in addition.
