Patent number: 4444930Abstract: The invention relates to a fire-resistant synthetic resin composition containing a polycarbonate, more specifically a bisphenol A derivative, a phosphorous fireproofing additive derived from phosphonic acid, and possibly other additives and/or fillers.The fireproofing additive is a Li, Na or K hemiester of a phosphonic acid derived from an aromatic or cycloaliphatic hydrocarbon, or from a polynuclear aromatic compound, and is added at the rate of 0.01 to 0.4 weight % in relation to polycarbonate. This small amount of additive improves the fire-resistant properties of the polycarbonate, without affecting its mechanical properties.Type: GrantFiled: August 24, 1982Date of Patent: April 24, 1984Assignee: Ato ChimieInventors: Bernard Guerin, Pierre Poisson, Georges Sturtz
