Polymerization processes and polymers made therefrom

A method for producing a polyolefin comprising:

• a. contacting a first composition and a second composition in a feed line to form a third composition, wherein:
• i. the first composition comprises:
• 1. a first bimetallic catalyst, which is a contact product of i) a hafnocene catalyst, ii) a first zirconocene catalyst, iii) a support, and iv) an activator, wherein a mol ratio of hafnium to zirconium is from 95:5 to 70:30, and
• 2. a diluent,
• ii. the second composition comprises a second zirconocene catalyst, which is the same as or different from the first zirconocene catalyst, and a solvent, wherein the second zirconocene catalyst is dissolved in the solvent to form a solution;
• and
• iii. the third composition comprises a second bimetallic catalyst having mol ratio of hafnium to zirconium of from 85:15 to 50:50
• b. introducing the third composition from the feed line into a gas-phase fluidized bed reactor;
• c. introducing a slurry comprising continuity agent into the gas-phase fluidized bed reactor;
• d. introducing feed components into the gas-phase fluidized bed reactor, the feed components comprising hydrogen, ethylene, and a C3 to C12 alpha olefin comonomer;
• e. exposing the third composition and the feed components to polymerization conditions comprising:
• i. a hydrogen concentration in a range of from 50 ppm to 2000 ppm,
• ii. an ethylene concentration in a range of from 35 mol % to 95 mol %,
• iii. a comonomer concentration in a range of from 0.2 mol % to 2 mol %,
• iv. a reactor pressure in a range of from 200 psig to 500 psig, and
• v. a reactor temperature in a range of from 100 degrees F. and 250 degrees F., and
• f. obtaining a polyolefin.
