1. An improved method for polymerizing one or more polyolefins in the presence of a transition metal catalyst in at least one gas phase reactor having a straight section and an expanded section, the improvement comprises generating a flow of gas or gas-solids tangentially to one or more interior surfaces in the expanded section of the reactor to reduce particle build-up.
