Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polycarbonate composition filled with talc which excellent flame resistance, and additinally has, even at small wall thicknesses, improved rigidity, remarkably good resistance to stress cracking (that is resistance to chemicals), and low tool abrasion and low coating formation during processing.SOLUTION: The polycarbonate compositions contain an impact modifier, at least one phosphorus-containing flameproofing agent, and highly pure talc having an MgO content of from 28 to 35 wt.% and an SiOcontent of from 55 to 65 wt.%.
