Char-forming polymer compositions. Reineke, Charles E. (Dow Chemical Co., USA). U.S. US 4038245 26 Jul 1977, 8 pp. (English). (United States of America).Several substances like 64168-06-5 may be metioned in this study. CODEN: USXXAM. CLASS: IC: C08K005-41. NCL: 260045700S. APPLICATION: US 76-688862 21 May 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Tertiary hydrocarbyl esters of trifluoromethanesulfonic acid are char-forming fire-retardant additives for plastics. Thus, 25.5 g trifluoromethanesulfonic anhydride [358-23-6] in CH2Cl2 was added over 1.5 h to 26.0 g 3-bromo-2,2-bis(bromomethyl)-1-propanol [1522-92-5] and 6.3 g pyridine in 75 mL CH2Cl2 at 0.degree. to give 3-bromo-2,2-bis(bromomethyl)propyl trifluoromethanesulfonate (I) [64168-01-0] in 91.5% yield. A maleic anhydride-styrene copolymer (II) [9011-13-6] contg. 10.3% I had an Underwriters Lab. rating 94V-0 and av. flame time <1 s. .

Tribromoneopentyl phosphorus reactive flame retardants. Weil, Edward D. (Stauffer Chemical Co., USA). U.S. There are some commonly used reagents like 59887-66-0 in this article. US 4049754 20 Sep 1977, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07F009-09. NCL: 260952000. APPLICATION: US 76-726077 23 Sep 1976. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Fireproofing agents, [(BrCH2)3CCH2O]2P(O)R where R = CH:CH2, ClCH2, NHPh, NH2, MeNH, HOCH2CH2, alkenyloxy, alkoxy, for cotton textiles and plastics are prepd. from tribromoneopentyl alc. (I) [1522-92-5]. For example, chloromethylphosphonic dichloride is added to I to give bis(tribromoneopentyl) chloromethylphosphonate [59887-62-6] which gives cotton a wash-fast fireproof finish. .
