Ethylene copolymer rubber. (Mitsui Petrochemical Industries, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58196215 A2 15 Nov 1983 Showa, 9 pp. (Japanese). (Japan).Chemical with cas number 7727-18-6 also plays role. CODEN: JKXXAF. CLASS: IC: C08F210-16; C08F004-62. APPLICATION: JP 82-77575 11 May 1982. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Ethylene copolymer elastomers are prepd. in the presence of V compds. and reaction products of organoaluminum with hydrocarbon polymers having no.-av. mol. wt. 500-20,000 and OH and/or CO2H groups. Thus, 0.25 mmol Et3Al2Cl3 and 0.5 mequiv. (based on OH) hydrogenated hydroxy-terminated polybutadiene (mol. wt. 3050) in 250 mL n-hexane were stirred 10 min at 25°, treated with 90 L/h ethylene and 210 L/h propene in the presence of 0.05 mmol VOCl3 at 30° for 30 min to give 4.2 g rubber of 59.1% ethylene units having intrinsic viscosity (135°, Dekalin) 5.02 dL/g, compared with 3.0 g and 4.45 dL/g, resp., for a similar run in the presence of unmodified Et3Al2Cl3. .
