KINETIC STUDY OF GAS-PHASE POLYMERIZATION OF PROPENE BY THE INHIBITION METHOD USING CARBON MONOXIDE

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 k;and the activation energy were determined from the experimentalresults. We concluded that the C;decreases with polymerization time and coincides with the decayrate of the polymerization.
