    摘要: Flame-resistant polycarbonate molding compositions containing halogen-free sulphonic acid salts of aromatic aldehydes or acetals of these aldehydes in quantities of about 0.005 to 10% relative to the total weight of the composition are disclosed. The compositions optionally further containing inorganic sulphates, exhibit flame retardance and little tendency to dripping in comparison to prior art compositions.

    摘要: A process for the production of polycarbonate foam moldings is disclosed. Accordingly, a composition is prepared comprising mixing a thermoplastic polycarbonate resin and 0.01 to 1 mole-% of a transesterification catalyst anda) 0.1 to 5 mole-% of an aromatic polycarboxylic acid, optionally along with about 0.1 to 5 mole-% of at least one member selected from the group consisting of aliphatic hydroxy carboxylic acids and aliphatic polyalcohols, orb) 0.1 to 5 mole-% of H.sub.2 O, optionally along with at about 0.1 to 5 mole-% of at least one member selected from the group consisting of aliphatic hydroxycarboxylic acids and an aliphatic alcohols, orc) the additives of said a) and b), ord) 0.1 to 5 mole-% of at least one member selected from the group consisting of diarylcarbonates and oligocarbonates,said percent based in every case on moles aromatic carbonate structural units ##STR1## in which --O--R--O is a diphenolate residue. The composition obtained is processed to foam moldings by injection molding or by extrusion at temperatures of 210.degree. C. to 340.degree. C.
