Storage-stable, prevulcanization-resistant rubber-textile-adhesive combination. Schubart, Ruediger; Albrecht, Klaus Dieter (Bayer A.-G., Ger.). Ger. Offen. DE 2634034 2 Feb 1978, 34 pp. (German). (Germany). CODEN: GWXXBX. 108-58-7 which is the cas registry number is also used here. CLASS: IC: C08L011-00. APPLICATION: DE 76-2634034 29 Jul 1976. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) Ca silicate, MgO, a HCHO donor, and a resorcinol deriv., such as an ester, urethane, or ether deriv., were added to rubber-based adhesive compns. to improve the adhesion to tire cords, such as rayon, nylon, and polyester cords. The adhesive contg. the resorcinol deriv. had better resistance to prevulcanization during processing, had better storage stability, and gave similar adhesion, compared with adhesives contg. resorcinol. Thus, Ca silicate 3.2, MgO 0.8, resorcinol diacetate [108-58-7] 4, and hexamethylolmelamine pentamethyl ether [13822-63-4] 2.3 parts were mixed with a vulcanizable adhesive contg. 100 parts polychloroprene. The mixt. had Mooney scorch time 21 min at 120°. A similar adhesive had a shelf life of >20 wk at 50°. .

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.
