Flame-resistant moulding materials based on thermoplastic aromatic
polyesters and polyesters carbonates, a process for their production
and their use in the production of moulded bodies
摘要:
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.
