Abstract
The kinetics of ethylene polymerization catalyzed by Cp2ZrCl2-different alu minoxanes was studied. More than one type of active site was presented in t he polymerization reaction based on an analysis of the GPC curves. A multip le active sites kinetic model (MSmodel) was proposed, Good agreements in po lymerization rate and variation of polydispersity were achieved for fitting the kinetic profiles with the MSmodel.
