Abstract:
Disclosed herein are polymerization processes for the production of olefin polymers. These polymerization processes use a catalyst system containing at least two activator-supports. One activator-support is a halided solid oxide, and the other activator-support is a sulfated solid oxide and/or phosphated solid oxide.
