Stabilization of elastic polymers to petroleum products: Stabilization of elastic polymers to petroleum products. (Ciba-Geigy A.-G., Switz.). Jpn. Kokai Tokkyo Koho JP 59078250 A2 7 May 1984 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L021-00; C08K005-24; C08K005-49. APPLICATION: JP 83-172845 19 Sep 1983. PRIORITY: US 82-419686 20 Sep 1982. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Elastic polymers can be stabilized by adding a metal salt of mono-Et (3,5-di-tert-butyl-4-hydroxybenzyl)phosphonate (metal = Ca, Zn, Mg, Co, or Ti) or I (R, R1 = C1-6-alkyl; R2 = H, C2-18-alkanoyl, acyl group to make I sym.; n = 0-5). Thus, nitrile rubber 100, carbon black 75, CaCO3 30, tris(butoxyethyl) phosphate 25, Sunolite (petroleum wax) 3, ZnO 5, and stearic acid 0.75 part were mixed for 4-5 min and 0.30 phr Irganox MD 1024 [32687-78-8] was added to the mixt., which was kneaded for 3 min. Santocure NS 0.75, Me tuads 1.75, and S 0.40 part were added to the mixt., which was molded at 157° for 10 min to give a 75-mil plate having tensile strength 1760 (initial) and 1880 psi (after 70 h) and elongation 425 (initial) and 215% (after 70 h).

A bifunctional antioxidant/metal deactivator for polyolefin wire insulation: A bifunctional antioxidant/metal deactivator for polyolefin wire insulation. Patel, A. (Addit. Dep., Ciba-Geigy Corp., Ardsley, N. Y., USA). Proc. Int. Wire Cable Symp., 26, 83-6 (English) 1977. CODEN: PIWSDG. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) The use of N,N'-bis[3-(3',5'-di-tert-butyl-4'-hydroxyphenyl)propionyl]hydrazine (I) [32687-78-8] in polyolefin wire insulation provided better oven aging at 100 and 120° than did mixts. of I and tetrakis[methylene-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]methan e (II) or II-N,N'-dibenzal oxalyldihydrazide. The I functioned both as an antioxidant and a metal deactivator. The I was also less sensitive to petrolatum exposure than the 2-component systems.
