Abstract
Olefins such as ethylene, propylene and butylene are polymerized, using Ziegler type catalysts, in the presence of solvents which have been purified by treatment with Ziegler catalyst components, prior to the addition of catalyst to the solvents or to the formation of catalyst therein. The Ziegler type catalysts and components thereof may be those disclosed in Specifications 799,392, 799,823 and 801,031, and particular components used in the purification are titanium tetrachloride and/or aluminium diethyl monochloride. The solvents specified are pentane, hexane, heptanes, iso-octane, cyclohexane, benzene, toluene and dichlorobenzene. Preferably, the solvents are pretreated, before purifying as above, by successively washing with concentrated sulphuric acid, water, alkaline solution, and then water again, followed by drying (e.g. with CaCl2 and/or Na), and then optionally distilling or treating with and adsorbent such as alumina. The olefins may also be purified by treatment with a catalyst component as above, e.g. aluminiumtriethyl or -diethyl monochloride, preferably in hydrocarbon solution. In an example, ethylene is added continuously during the polymerization. Purification of the polyolefins obtained and deactivation of catalyst, e.g. with methanol, methanolic hydrochloric acid and water (which may contain ethylene oxide/octyl phenol condensate as surfactant), is less troublesome and the products are of more constant molecular weight. Shaped objects and copolymers are claimed. Specifications 619,231 and 742,642, [Group IV (b)], also are referred to.
