The kinetics of ethylene polymerization catalyzed by Cp 2ZrCl 2 – different aluminoxanes was studied. More than one type of active site was presented in the polymerization reaction based on an analysis of the GPC curves. A multiple active sites kinetic model (MSmodel) was proposed. Good agreements in polymerization rate and variation of polydispersity were achieved for fitting the kinetic profiles with the MSmodel.
