Improved, nonopaque, flame-resistant polycarbonate composition
Improved, nonopaque, flame-resistant polycarbonate composition. Mark, Victor (General Electric Co., USA). Ger. Offen. DE 2744018 20 Apr 1978, 24 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08L069-00. PRIORITY: US 76-733015 15 Oct 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) A polycarbonate was mixed with Na 4-(phenylthio)benzenesulfonate [63316-44-9], K 3-(phenylsulfonyl)benzenesulfonate (I) [63316-43-8], 4,4'-disulfodiphenyl sulfone di-K salt [66671-18-9], Na 2,5-dichlorobenzenesulfonate [5138-93-2], Na salt of sulfonated polystyrene, or a similar compd. and with an alkali metal halide to prep. fire-resistant polycarbonates with good transparency. 63316-44-9 is also in the experiment. Thus, a bisphenol A-phosgene copolymer [25971-63-5] contg. 0.1% I and 0.2% KBr was fire resistant (VO in UL 94 test), did not drip during exposure to flame, and had light transmission 82.2%, compared with 86.2% without I and KBr. . 63316-44-9 are also occured in this study..

PRIORITY: US 75-626939 29 Oct 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Bisphenol A polycarbonate (I) [24936-68-3] is flameproofed to UL-94 stds. V-O, V-I, or V-II by addn. of 0.1-0.5% Na, K, Ca, or Ba diphenyl sulfone sulfonate deriv. of n 1.54-1.65 to provide compns. with .gtoreq.72% light transmission. Thus, I contg. 0.1% 3-PhSO2C6H4SO3K [63316-43-8] has light transmission 89%, self-extinguishing time 3. 63316-42-7 which is the cas registry number is also used here.6 s, no dripping, and rating V-O, compared to 89%, 24s, 13 drops (for 5 specimens), and rating flammable, resp., for pure I or I contg. 1% (C6Br5)2O. .
