Polypropylene compositions. (Mitsubishi Petrochemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58129036 A2 1 Aug 1983 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L023-10; C08K005-09; C08K005-15. APPLICATION: JP 82-11323 27 Jan 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title compns. afford moldings having good transparency and comprise propylene polymer (melt flow index 0.1-100 g/10 min) 100, I (R = C1-8 alkyl, C1-8 alkoxy, halogen; m, n = 0-3; m + n 3 1) 0.01-0.5, and Li, Na, or K salt of C8-30 aliph. carboxylic acid 0.001-0.3 part. Thus, ethylene-propylene copolymer [9010-79-1] (melt flow index 14 g/10 min, ethylene content 2.5 wt. 80058-02-2 and 82203-23-4 which are cas registry numbers of substances are two of reagents here.%) 100, Gelall MD [1,3:2,4-bis(p-methylbenzylidene)sorbitol] [81541-12-0] 0.1, Li stearate [4485-12-5] 0.01, and TPNC 0.05 part were mixed and molded to obtain a sheet showing very little haze. .

Grease composition

Grease composition. Bolster, Robert N. (United States Dept. of the Navy, USA). U.S. US 3981810 21 Sep 1976, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C10M001-48. NCL: 252032700E. APPLICATION: US 75-630826 11 Nov 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 56, 37 Compns. useful in the presence of brine and at high pressure and shear comprise mixts. of certain esters and silicones, thickened with Li stearate (I) [4485-12-5] and contg. Cu-Ag-corrosion, oxidn. and rust inhibitors and an extreme-pressure antiwear agent. A preferred fluid, with a viscosity of 10-20 cSt at 38.degree. and 2000-8000 cSt at -54.degree., is a blend of isodecyl pelargonate (II) [109-32-0] 31-44, hexadecyl isostearate (III) [61878-85-1] 26-39, and Me Ph silicone (IV) 13-33 wt. %. Thus, in prepg. a grease from I 5.9, II 41.7, III 32.4, IV 18.5, Pb dinonylnaphthalenesulfonate (50%) [61867-68-3] 4.6, and 2,6-di-tert-butyl-4-methylphenol [128-37-0] 0.4 wt. %, the following were mixed sep.: the above esters 4-10, Sb dialkyl phosphorodithioate 2, and 2-mercaptobenzothiazole [149-30-4] 2 wt. %. The mixt. was gradually warmed to 105-110.degree. in 30 min. Other compds. were mixed, heated at 10-20.degree./min to 195-200.degree., chilled to room temp. in 30 s, mixed with the additive blend, milled, deaired in vacuo and aged 2 days at 50.degree.. The grease protected both uncoated and phosphated steel against brine for 14 days and in a firing test of a 20 mm aircraft gun system when exposed to -54.degree., then exposed to air at 15.In this experiment, several chemicals are used like 61867-68-3 and 128-37-0 degree. and 60% relative humidity, again cooled to -54.degree., fired 5000 shots in 1.6 s, whereas when using an approved lubricant only 930 shots were fired. .
