Abstract
An improved method for polymerizing one or more polyolefins in the presence of a transition metal catalyst in at least one gas phase fluidized bed reactor, the improvement comprises generating at least one low frequency, high pressure sound wave inside a reactor system, which wave has sufficient frequency and pressure to dislodge and/or prevent particle build-up on interior surfaces of the reactor system.
