The inhibition method using CO to determine the active center concentration C* in olefin poly-merization and the kinetics of gas-phase polymerization of propene were studied. The reliabilityof the method when used in gas-phase polymerization of propene is proved and the influencing fac-tor of the method is found to be the "repeating inhibition" of CO to the active centers. The C*
the rate constant kP and the activation energy were determined from the experimentalresults. We concluded that the C* decreases with polymerization time and coincides with the decay rate of the polymerization.
