Thermoplastic polycarbonate moulding compounds with flame-resistant
properties
摘要:
Thermoplastic polycarbonate moulding compounds containing 40 to 90 parts by weight of a thermoplastic aromatic polycarbonate; 0 to 80 parts by weight of a copolymer or polycondensate consisting of 0 to 50 parts by weight of a thermoplastic copolymer of 50 to 95% by weight of styrene, .alpha.-methylstyrene, styrene alkylated in the nucleus, halogenated styrene or mixtures thereof and 5 to 50% by weight of acrylonitrile, methacrylonitrile, alkyl acrylate, alkyl methacrylate, maleic acid anhydride, N-substituted maleiimide, vinyl acetate or mixtures thereof and/or 0 to 80 parts by weight of a thermoplastic polyalkylene terephthalate; 1 to 25 parts by weight of graft polymer prepared from 5 to 90 parts by weight of a mixture of: 50 to 95% by weight of styrene, .alpha.-methylstyrene, halogenated styrene, styrene alkylated in the nucleus, methyl methacrylate or mixtures thereof and 5 to 50% by weight of (meth)acrylonitrile, methyl methacrylate, maleic acid anhydride, N-substituted maleiimide or mixtures thereof on 10 to 95 parts by weight of a rubber having a glass temperature TG of .ltoreq.10.degree. C.; 1 to 30 parts by weight of phosphoric acid esters of phenols, bisphenols and/or polyphenols; and 0.05 to 5 parts by weight of anti-dripping agent, the total weight of the above amounting to 100 parts by weight, wherein the anti-dripping agent is aromatic polyamides or polyimidamides (aramides) in the form of fibres or powders or deposited on carriers.
