Ultrahigh-molecular weight polyethylene compositions

Ultrahigh-molecular weight polyethylene compositions. (Sekisui Chemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 60001245 A2 7 Jan 1985 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C08L023-06. ICS: C08K005-01; C08K005-03; C08K005-09. APPLICATION: JP 83-111152 20 Jun 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 38 The title compns. contain polyethylene [9002-88-4] (mol. wt. 31 ′ 106), arom. ring compds. and their derivs. (chlorinated or unchlorinated), and C12-32 alkanoic acid salts. The compns. have sufficiently low viscosities for extrusion molding without affecting other properties. Thus, polyethylene (mol. wt. 32 ′ 106) 100, cyclohexylbenzene [827-52-1] 20, and Ca montanate [52258-47-6] 2 parts were extruded into a sheet previously obtainable only by compression molding of polyethylene.

Pyrolysis-gas chromatography-mass spectrometry of model compounds from coal hydrogenates

Pyrolysis-gas chromatography-mass spectrometry of model compounds from coal hydrogenates. Part II. Uncondensed bicyclic hydrocarbons. Braekman-Danheux, C. (Fac. Sci. Appl., Univ. Libre Bruxelles, Brussels 1050, Belg.). J. Anal. Appl. Pyrolysis, 6(2), 195-200 (English) 1984. CODEN: JAAPDD. ISSN: 0165-2370. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 24 Uncondensed bicyclic compds. (e.g., cyclohexylcyclohexane [92-51-3], cyclohexylbenzene [827-52-1], 1-phenyl-1-cyclohexene [771-98-2], and 1,2-dicyclohexylethane [3321-50-4]) were thermally cracked in ref. to the prodn. of single-ring arom. hydrocarbons from hydrogenated coal liqs. When both rings are fully hydrogenated, the initial cracking is a rupture of the intercyclic bond, which is followed by dehydrogenation of the fragments to the single-ring aroms. When 1 ring is hydrogenated, however, the primary reaction is a rupture of the satd. ring, yielding naphthalene and indene in addn. to single-ring aroms.
