Abstract (en)
[origin: WO2022263335A1] Described are thermoplastic compositions on the basis of aromatic polycarbonate having a high comparative tracking index, a good flame retardancy and high heat deflection temperature. The compositions contain a combination of PMMI, phosphorus-containing flame retardant and fluorine-containing anti-dripping agent.
