Improved flame-resistant polycarbonate composition: Improved flame-resistant polycarbonate composition. Mark, Victor (General Electric Co., USA). Ger. Offen. DE 2745592 20 Apr 1978, 23 pp. (German). (Germany). CODEN: GWXXBX. 515-42-4 which is the cas registry number of some chemical is mentioned. CLASS: IC: C08L069-00. PRIORITY: US 76-733017 15 Oct 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) A polycarbonate was mixed with Na benzenesulfonate (I) [515-42-4], 4-sulfodiphenyl ether Na salt [15336-66-0], K 2-naphthalenesulfonate [21409-32-5], 3,3'-disulfodiphenyl sulfone di-K salt [63316-33-6], or a similar compd. 515-42-4 which is the cas registry number is also used here. and with Na pentachlorobenzenesulfonate (II) [39569-18-1], K 4-bromobenzenesulfonate [66788-58-7], F3CSO3K [2926-27-4], Na 5-chlorothiophene-2-sulfonate [66788-59-8], 2,3,4,5,6-pentachloro-4'-sulfodiphenyl sulfide Na salt [66850-78-0], or a similar compd. to prep. fire-resistant plastics. Thus, a bisphenol A-phosgene copolymer [25971-63-5] contg. 0.1% I and 0.1% II had fire-resistance V-O (UL 94 test), compared with V-II for a polycarbonate contg. either 0.2% I or 0.2% II. ..
