Abstract (en)
[origin: WO2021038517A1] A flame retardant polycarbonate composition comprising: 60.0-99.9 weight percent of a poly(carbonate-bisphenol phthalate ester) comprising 1-50 weight percent of aromatic carbonate units and 50-99 weight percent of bisphenol phthalate ester units, each based on the sum of the weight of the carbonate units and the bisphenol phthalate ester units; 0.1-0.5 weight percent of a C1-16 alkyl sulfonate salt flame retardant; 0-30.0 weight percent of a homopolycarbonate; wherein a molded sample of the flame retardant polycarbonate composition has improved thermal and flammability performance.
