Patent number: 8916664Abstract: An ethylene oligomerization catalyst that oligmerizes ethylene to a series of ?-olefins and that has a Schulz-Flory constant of about 0.75 to 0.995 produces a stream of ?-olefins.

Patent number: 8003740Abstract: Method of preparing olefin polymers, which comprises the polymerization of at least one ?-olefin in the presence of a hybrid catalyst to produce a polymer comprising at least a higher molecular weight polymer component and a lower molecular weight polymer component in the presence of water in an amount of from 2 to 100 mol ppm and/or carbon dioxide in an amount of from 2 to 100 mol ppm, in each case based on the total reaction mixture, in order to alter the ratio of the higher molecular weight polymer component to the lower molecular weight polymer component. This enables the ratio of the higher molecular weight component to the lower molecular weight component to be controlled selectively.Type: GrantFiled: July 13, 2006Date of Patent: August 23, 2011Assignee: Basell Polyolefine GmbHInventors: Shahram Mihan, Rainer Karer, Harald Schmitz, Dieter Lilge
