Electroactive polymers. Kurkov, Victor P. (Chevron Research Co. , USA). Ger. Offen. DE 3341627 A1 17 May 1984, 48 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08F008-00; C08F008-04; C08F008-06; C08F034-00; C08G073-06; C08L045-00; C08L079-04. APPLICATION: DE 83-3341627 17 Nov 1983. PRIORITY: US 82-442394 17 Nov 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 76 Flexible polymers with reversible elec. activity contain tricyclic (5:6:5) heterocyclic units contg. 2 heteroatoms (N, O, S, Se, Te) in each 5-membered ring and sufficient ionic doping agent for charge compensation. Thus, heating a stirred mixt. of 4,6-diaminoresorcinol [15791-87-4] (prepd. by nitration of resorcinol diacetate [108-58-7] and hydrogenation) 1.562, terephthalic acid 1.2258 and polyphosphoric acid 128 g for 2 h at room temp., 16 h at 55°, 3 h each at 70, 95, 130, 150, 170, and 185°, and 16 h at 200° gave poly[benzo[1,2-d:5,4-d']bisoxazole-2,6-diyl]-p-phenylene] (I) [60871-72-9] with intrinsic viscosity (MeSO3H, 30°) 1.7 kL/g. A Pt wire coated with I from a 2.5% soln. in MeSO3H and dipped in a 0.1 M MeCN soln. of Et4N+ BF4- [429-06-1] became neg. charged and was made elec. active by application of a voltage of -2.1 V in the presence of an electrolyte supplying charge-compensating, doping ions.

Molecular composites containing rigid aromatic polymers finely dispersed as reinforcing polymers in matrix polymers

Molecular composites containing rigid aromatic polymers finely dispersed as reinforcing polymers in matrix polymers. Akita, Koji; Kobayashi, Hiroto (Honda Motor Co Ltd, Japan). Jpn. Kokai Tokkyo Koho JP 09025419 A2 28 Jan 1997 Heisei, 25 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C08L101-00. ICS: C08L077-10; C08L081-00. APPLICATION: JP 1995-197948 12 Jul 1995. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title composites showing no coagulation of the dispersed polymer particles during thermoforming and having excellent mech. strength contain microparticles of heteroarom. copolymers. A copolymer from 2,5-bis(2-cyanoethylthio)-1,4-benzenediamine, 3,4'-diaminodiphenyl ether, and 2-chloroterephthaloyl dichloride was stirred with arom. polyamide TX-1 in N-methylpyrrolidone, sprayed into EtOH, vacuum-dried, heat-treated at 330° for 30 min for polybenzothiazole ring formation, and hot-pressed to give a specimen with bending modulus 644 kg/mm2 and bending strength 6.8 kg/mm2.Except for chemicals metioned above, 187528-02-5 and 15791-87-4 are also used. .
