SU 439168 28 Feb 1978 From: Otkrytiya, Izobret., Prom. Obraztsy, Tovarnye Znaki 1978, 55(8), 245. (Russian). (Union of Soviet Socialist Republics). CODEN: URXXAF. CLASS: IC: C08G031-34. APPLICATION: SU 70-1399917 2 Feb 1970. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) Vulcanizates with reduced permanent set are prepd. by polycondensation of stoichiometric amts. of an organocyclosilazane (A) with an organosilicon diol (B) at 100-80°. The A component can be hexamethylcyclotrisilazane [1009-93-4], octamethylcyclotetrasilazane [1020-84-4], or octamethyl-1,5-dioxa-3,7-diaza-3,7-dihydro-2,4,6,8-tetrasilacyclooctan e [2329-04-6] and the B component can be HO(SiRR1O)xSiRR1OH, where R = Me; R1 = fluoroalkyl, fluoroaryl, cyanoalkyl; and x = 200-50,000.

Coating continuous filaments. Albarino, Robert Vincent; Torza, Sergio (Bell Telephone Laboratories, Inc., USA). U.S. US 4073974 14 Feb 1978, 13 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: B05D001-18. NCL: 427163000. APPLICATION: US 75-600280 31 Jul 1975. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Mech. distortions of optical glass fibers are prevented by coating the fibers with hexamethylcyclotrisilazane [1009-93-4] or octadecyltriethoxysilane [7399-00-0]. The fibers are passed through a fluid-filled container contg. upper and lower constrictive openings. A decreased pressure is maintained in the container to prevent flow of the coating from the container. The coatings are thermally cured.
