Thermoplastic foam mixtures. Niznik, George Elliot (General Electric Co., USA). Ger. Offen. DE 2637736 3 Mar 1977, 30 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08J009-06. PRIORITY: US 75-608451 28 Aug 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 28 3,6-Dihydro-5-phenyl-1,3,4-oxadiazin-2-one (I, R = H) [62501-39-7] and I (R = Ph) [19836-49-8] were used as blowing agents for polycarbonates, polyolefins, polyamides, and other thermoplastics. The blowing agents did not degrade the polymers during extrusion and foaming. Thus, MeCOPh [98-86-2] was brominated and converted to HOCH2COPh [582-24-1] which was treated with H2NNHCO2Me [6294-89-9] and cyclized to prep. I (R = H). A polycarbonate had intrinsic viscosity 0. 9003-53-6 and 63394-03-6 are also in the experiment.54 dL/g initially and 0.53 dL/g after mixing with 0.6% I (R = H) and extrusion at 305.degree. to give foam with d. 0.86. .

Castable smoke- or fog-producing pyrotechnic composition

Castable smoke- or fog-producing pyrotechnic composition. Sedat, Georges (Etat Francais, Fr.). Ger. Offen. DE 3326913 A1 9 Feb 1984, 14 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C06D003-00. APPLICATION: DE 83-3326913 26 Jul 1983. PRIORITY: FR 82-13157 28 Jul 1982. 28301-91-9 and 4114-31-2 which are cas registry numbers are also used here. DOCUMENT TYPE: Patent CA Section: 50 (Propellants and Explosives) A colored smoke- and fog-forming pyrotechnic mixt. for fireworks and ammunition contains KClO3 or NaClO3 10-25, guanidine nitrate [506-93-4] 10-30, synthetic aliph. epoxy resin (I) [28301-91-9] from the condensation of epoxypropanol and propanetriol) 10-35, org. plasticizer 1-15, hardener ￡3, sublimating org. dye 25-30, metal oxide ￡5, and C1-3 alkyl carbazate 2-15%. The mixt. can be cast, hardened, and stored for subsequent use. Thus, a stable yellow smoke was obtained for 8 min from a 0.5 kg mixt. of KClO3 21, guanidine nitrate 17, yellow dye Organol 36, I 16, ethanediol [107-21-1] 5, ethanolamine [141-43-5] 2, and Me carbazate [6294-89-9] 3%. .
