Flame-resistant olefin polymer compositions. Suzuki, Hiroshi (Japan ). Japan. Kokai JP 52017547 9 Feb 1977 Showa,9 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L023-02. APPLICATION: JP 75-93835 1 Aug 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) A flame-resistant olefin polymer compn. is prepd., contg. a halogenated isocyanurate deriv., Sb2O3, and a metal inorg. compd. Thus, a mixt. of polyethylene [9002-88-4] 100, tris(2,3-dibromopropyl) isocyanurate (I) [52434-90-9] 6, Sb2O3 3, and Al(OH)3 1 part was extruded at 135.There are some commonly used reagents with their cas registry numbers 15899-41-9 and 9002-88-4 in this article.degree. to give chips which were pressed at 150.degree. and 150 kg/cm2, giving a product with improved flame resistance compared with a control when C6Br6 instead of I, Sb2O3, and Al(OH)3 was used as flame retardant. .

DE 3318105 A1 9 Feb 1984, 18 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D01F006-54; D01F001-10. APPLICATION: DE 83-3318105 18 May 1983.There are some reagents with their cas registry numbers 1314-13-2 and 77193-40-9 are used in this study. PRIORITY: AT 82-1979 19 May 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Dry-spun fireproof acrylic fibers are manufd. by dry spinning a polymer contg. 385% acrylonitrile units and 15-40% tris(2,3-dibromopropyl)isocyanurate (I) [52434-90-9] and 0-10% of a compd. having a synergistic effect on the fireproofing activity of I. Thus, an acrylic fiber was dry spun from a compn. contg. I 7.40, Sb2O3 0.93, polyacrylonitrile 25.33, and DMF 66.34 wt.% into a spinning cell at 100-210°, stretched, washed and dried to give a fiber contg. 29.2% I and 3.7% Sb2O3. The fiber had titer 3.5 dtex, tenacity 24 cN/tex, stretch 34%, degree of whiteness 48 BE, and limiting oxygen index (LOI) 29.5, whereas a similar fiber contg. no additive had LOI 18. .
