Polyphenol allyl derivatives useful in polymerization and crosslinking. Laval, Francois; Madec, Pierre Jean; Marechal, Ernest (Commissariat a l'Energie Atomique , Fr.). Eur. Pat. Appl. EP 88027 A1 7 Sep 1983, 29 pp. DESIGNATED STATES: R: DE, GB, IT, NL. (French). (European Patent Organization). CODEN: EPXXDW.Several reagents with their cas registry numbers 88266-85-7 and 63119-89-1 are used here. CLASS: IC: C07C043-23; C07C049-84; C07C069-96; C07C147-06; C08F016-32; C08G018-32; C08G077-42; C07C041-03. APPLICATION: EP 83-400429 2 Mar 1983. PRIORITY: FR 82-3522 3 Mar 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 25 The title compds. are prepd. by the reaction of polyphenols with allyl glycidyl ether (I) [106-92-3]. Thus, adding 10 g C12H25NMe2 to 228 g bisphenol A [80-05-7] and 228 g I stirred at 120° and stirring 2 h at this temp. gave 466 g bisphenol A bis[3-(allyloxy)-2-hydroxypropyl] ether [63119-89-1]. Heating 456 g this compd., 134 g O(SiHMe2)2, and 1 mL 1% H2PtCl6 slowly to and 1 h at 70° gave a transparent block polymer [88266-84-6], mol. wt. >10,000, which was readily sol. in org. solvents. .

Stiff plastic laminates

Stiff plastic laminates. (Matsushita Electric Industrial Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58197047 A2 16 Nov 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B32B027-04. ICA: B32B027-00; B32B027-28; B32B027-30; B32B027-36; C08J005-24. APPLICATION: JP 82-80422 12 May 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Fiber-reinforced plastic laminates having excellent stiffness and flexural strength comprised polycarbonate, polyolefins, poly(phenylene sulfide), olefin-vinyl alc. copolymer, polyether-sulfone, and/or acrylonitrile-styrene copolymer [9003-54-7] sheets, reinforcing fiber layers, and compds. contg. C-C double bond and/or epoxy groups. Thus, glass fiber cloth sheets were treated with 1.0% aminosilane coupling agents, then 5% allyl glycidyl ether (I) [106-92-3], heated to 80° for ~1 h, then laminated between 2-mm polycarbonate sheets and pressed at 270° and 100 kg/cm2 for 15 min to obtain a laminate contg. 55 vol.In this experiment, several chemicals are used like 9003-54-7 and 557-75-5 % fibers, which had flexural modulus 427,000 kg/cm2 and flexural strength 7100 kg/cm2, compared with 330,000 and 6500, resp., for laminates prepd. identically without I. .
