发明名称 FIRE RESISTANT POLYCARBONATE MOULDING COMPOSITIONS COMPRISING UV-ABSORBERS AND SHOWING A SMALL REDUCTION OF MOLECULAR WEIGHT UPON PROCESSING
摘要 The present invention relates to flameproofed, UV resistant polycarbonate moulding compositions with good melt stability and a high proportion of free, reactive UV absorbers, wherein the polycarbonate compositions comprise A) at least one polycarbonate with an average molecular weight M w of 18,000 to 40,000, B) at least one alkali or alkaline earth salt of an organic flame retardant consisting of diphenylsulfone, alkali or alkaline earth diphenylsulfone sulfonate and alkali or alkaline earth diphenylsulfone disulfonate, and C) one or more reactive UV absorbers, and wherein B) comprises diphenylsulfone in a proportion of 1.10 wt. % to 2.50 wt. %, based on the total mass of component B).
