Abstract
In an embodiment, a method for producing a polyolefin includes contacting a first composition and a second composition in in a line to form a third composition, wherein: the first composition comprises a contact product of a first catalyst, a second catalyst, a support, a first activator, and a diluent, wherein the mol ratio of second catalyst to first catalyst is from 60:40 to 40:60, the second composition comprises a contact product of the third catalyst, a second activator, and a second diluent, and the third composition comprises a mol ratio of the third catalyst to the second catalyst to the first catalyst of from 10:35:55 to 60:15:25, such as 30:20:30; introducing the third composition from the line into a gas-phase fluidized bed reactor; exposing the third composition to polymerization conditions; and obtaining a polyolefin.
