Abstract (en)
[origin: WO2012059531A1] The invention relates to flameproofed UV-resistant polycarbonate molding materials having a good melt stability and a high fraction of free, reactive UV absorbers, wherein the polycarbonate compositions contain A) at least one polycarbonate having an average molecular weight M¯ w from 18,000 to 40,000, B) at least one organic flameproofing agent comprising diphenyl sulfone, alkali or alkaline-earth diphenyl sulfone sulfonate, and alkali or alkaline-earth diphenyl sulfone disulfonate, and C) one or more reactive UV absorbers, and wherein B) comprises diphenyl sulfone in a fraction from 1.10 wt % to 2.50 wt %, relative to the total mass of the component B).
