ABSTRACT:
Aromatic polyesters and polyestercarbonates based on diphenols and iso- and/or terephthalic acids become flame-proof if admixed with small quantities of ammonium or alkali metal salts of inorganic or organic acids and optionally halophthalimides and optionally polytetrafluoroethylene. The mechanical and chemical properties of the polyester (carbonates) remain unchanged.
