ABSTRACT:
Disclosed is a process for polymerizing olefins. The process comprises polymerizing one or more olefins with a single-site catalyst in two or more polymerization stages. The catalyst comprises a transition metal complex, an activator, and a hydroxyl functional polymer. The complex, the activator, or both are chemically bound to the hydroxyl functional polymer.
