摘要
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 an expanded section, the improvement comprising generating a tangential flow of gas or gas-solids in the expanded section of the gas phase reactor to reduce fines entrainment into the gas cycle system and to reduce or remove solid particle build-up on one or more interior surfaces of the expanded section of the reactor.
