Heat stabilizers for fluoropolymers: Heat stabilizers for fluoropolymers. (Mitsubishi Rayon Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58208344 A2 5 Dec 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L033-04; C08K005-37. APPLICATION: JP 82-92286 31 May 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title compns. contain polymers contg. >70% fluoroalkyl methacrylate and 0. 68-11-1 and 33007-83-9 which are cas registry numbers of chemicals are mentioned.01-5 phr mercaptan. Thus, 2:100 Me methacrylate-2,2,2-trifluoroethyl methacrylate copolymer [56806-67-8] contg. 0.2% HS(CH2CH2O)2CH2CH2SH [14970-87-7] had good resistance at 270° in air and gave a transparent film. .

Optical fibers: Optical fibers. (Mitsubishi Rayon Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59002002 A2 7 Jan 1984 Showa, 9 pp. (Japanese). 14970-87-7 and 10193-99-4 are cas registry numbers. These chemicals are also mentioned in this article. (Japan). CODEN: JKXXAF. CLASS: IC: G02B005-14. ICA: D01F008-10. APPLICATION: JP 82-111309 28 Jun 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Optical fibers with reduced voids are prepd. by melt spinning together a polymer contg. Me methacrylate (I) unit as core and a mixt. contg. a polymer of fluoroalkyl methacrylate or its copolymer with a vinyl monomer and a mercaptan heat stabilizer as sheath. Thus, 100 parts 2,2,2-trifluoroethyl methacrylate was copolymd. with 2 parts I to give a copolymer (II) [56806-67-8]. A compn. contg. II and 0.2% (on II wt.) triethylene glycol dithiol [14970-87-7] as sheath and poly(Me methacrylate) [9011-14-7] as core were spun together at 250° to give optical fibers without voids. .
