(Japan).Several reagents with their cas registry numbers 37279-76-8 and 53860-54-1 are used here. CODEN: JKXXAF. CLASS: IC: C08G018-00. APPLICATION: JP 75-69635 11 Jun 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) An epoxy resin compn. with improved heat and flame resistance was prepd. Thus, a mixt. of ECN 1273 [37279-76-8] 80, DER 542 [33294-14-3] 20, naphthalene-1,5 diisocyanate [3173-72-6] 109, imidazole tetraphenyl borate (I) [53831-70-2] 2, quartz glass powder 510, stearic acid 3, and Sb2O3 2 parts was kneaded 5 min at 85.degree., molded and cured to give a flame-resistant product with good heat resistance. .

Study on the reinforcement of polyurethane elastomers based on hydroxyl-terminated polybutadiene

Study on the reinforcement of polyurethane elastomers based on hydroxyl-terminated polybutadiene. Part 1. The reinforcing effects of carbon blacks on liquid rubbers. Minoura, Yuji; Yamashita, Shinzo; Okamoto, Hiroshi; Ono, Katsuhiro; Nishimura, Toshihide; Nakai, Masayuki; Nomura, Saburo (Res. Inst. At. Energy, Osaka City Univ., Osaka, Japan). Nippon Gomu Kyokaishi, 51(1), 32-40 (Japanese) 1978. CODEN: NGOKAF. ISSN: 0029-022X. DOCUMENT TYPE: Journal CA Section: 38 (Elastomers, Including Natural Rubber) The tensile strength of polyisocyanate-crosslinked and carbon black-reinforced hydroxy-terminated liq. butadiene rubber increases with decreasing particle size of carbon black and is not affected much by the kind of polyisocyanates. Diisocyanates used were diphenylmethane 4,4'-diisocyanate [101-68-8], hexamethylene diisocyanate [822-06-0], and naphthalene 1,5-diisocyanate [3173-72-6]. Electron microscopic observation of the vulcanizates indicated that carbon black particles agglomerated to some extent.
