Preparation of laminated sheets

Preparation of laminated sheets. (Sumitomo Bakelite Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59103745 A2 15 Jun 1984 Showa, 6 pp. 93289-92-0 which is the cas registry number of one of substances is just one of reagents here. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B32B005-22; C08J005-24. ICA: C08K005-53; C09J003-00. APPLICATION: JP 82-198968 15 Nov 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Laminates are prepd. by impregnating a cellulose base material with a thermosetting resin contg. 0.5-2 phr water-sol. P compd. (RO)2P(O)(CH2)mNH2-n(ZOH)n (R = C1-4 alkyl; Z = C1-4 alkylidene, alkylene; n = 1, 2; m = 1-4) in addn. to an oil-sol. P compd., followed by drying and treating with heat and pressure. The sheets show excellent fire resistance, processability, and elec. properties. Thus, an oil-modified phenolic resin 100, (EtO)2P(O)CH2N(C2H4OH)2 [2781-11-5] 1, cresyl di-Ph phosphate [26444-49-5] 20, tetrabromobisphenol A [79-94-7] 25, melamine resin 25, and low-mol.-wt. polymethylolphenol resin 10 parts were mixed to prep. a resin compn., with which kraft paper was impregnated. Then, 8 of the prepregs were laminated, with Cu foil on one side, to obtain a laminated sheet which showed excellent phys. properties. .

Self-extinguishing polyurethane foams

Self-extinguishing polyurethane foams. Jenkner, Herbert; Buettgens, Walter (Chemische Fabrik Kalk G.m.b.H., Ger.). Ger. Offen. DE 2659503 6 Jul 1978, 7 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08L075-04. APPLICATION: DE 76-2659503 30 Dec 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) A polyurethane foam prepd. from a polyol, a diisocyanate, tetrachlorobisphenol A bis(2,3-dibromopropyl) ether (I) [65131-76-2], and (HOCH2CH2)2NCH2P(O)(OEt)2 (II) [2781-11-5] was self-extinguishing in burning tests. Thus, a mixt. of a polyether polyol (OH 415) 100, diphenylmethane diisocyanate 109, II 8.7, I 13.7, amine catalysts 2.5, silicone 0.9, and CFCl3 35 parts was used to prep. a nearly colorless polyurethane foam which was self-extinguishing during 30 s.
