Flame retardant polyalkylene terphthalate/polycarbonate compositions

Abstract

The present invention relates to polyalkylene terephthalate/polycarbonate compositions, containing A) 49 to 70 parts by weight aromatic polycarbonate, B) 21 to 40 parts by weight polyalkylene terephthalate with more than 2 carbons in the diol component, C) 6 to 25 parts by weight of a salt of a phosphinic acid, D) 0 to 24 parts by weight conventional additives, all parts by weight in the present application being standardised such that the sum of the parts by weight of components A+B+C+D in the composition adds up to 100, and which are distinguished by an optimum combination of low moulding shrinkage, high chemical resistance and good heat resistance together with good fire behaviour, the use of the polycarbonate compositions for the production of mouldings and the mouldings themselves.
