Abstract
Olefins are polymerized by contacting them under gas phase polymerization conditions with a catalyst composition. The composition comprises a bridged transition metal complex of specified formula. Olefin polymerization involves contacting them in the gas phase with a catalyst composition. The composition comprises a metal complex of formula (I) or (II).
