Abstract: Ethylene is polymerized in tubular reactors at 1,000-4,000 Atm and 150-300 DEG C. with feeding of cold ethylene at several successive points in the reactor and using up to 10-1% oxygen as catalyst which is added preferably in solution, to the cold ethylene in such amount that the oxygen concentration in the united gas stream at the points of confluence in the reactor is at least 0.5 x 10-3%, preferably 10-3-10-2%, and the speed of the reaction mixture in the reactor is at least 2.5 m/sec., e.g. up to 10 m/sec. The main ethylene stream may first be heated to e.g. 170-200 DEG C. The cold ethylene stream may be at 10-100 DEG C. and the oxygen concentration may be higher in the second cold ethylene stream than in the first. The oxygen may be dissolved in water, alcohols, e.g. methanol, or hydrocarbons e.g. benzene. The polyethylene may be used to form articles or tubular film.

Abstract: 940,903. Sealing rings. BADISCHE ANILIN- & SODA-FABRIK A.G. Feb. 26, 1962 [Feb. 27, 1961], No. 7356/62. Heading B5A. Sealing rings are formed with their sealing faces in contact with smooth lapped steel plates. The rings are moulded by injection moulding or bulk polymerization, the steel plates being incorporated in the mould. The rings may be made from a polyamide, polyethylene, polytetrafluoroethylene or polystyrene.
