Beschreibung
Zusammenfassung:	New ethylene-propylene copolymer oils containing 29-71 mol percent ethylene, the rest being at least substantially entirely propylene, said oils being of rich viscosity index, low pour point, and high stability, are produced from monoolefin mixtures containing ethylene and propylene employing specified vanadium-aluminum or titanium-aluminum Ziegler-type catalyst systems. Hydrogen under pressure is used with the vanadium-aluminum catalyst system to control molecular weight. Oils of lubricating oil viscosity can be produced directly, or after cracking higher molecular weight oil, said cracking usually, but not necessarily, followed by hydrogenating. Dewaxing can be employed to reduce pour point.
