Summary
Kinetic study was performed in short time propylene polymerization with a high activity-high stereospecificity catalyst system composed of MgCl2/TiCl4/PhCO2Et with AlEt3/PhCO2Et. The concentration of the active centers, [C *], the propagation rate constant, k p, and the chain transfer rate, r tr, were determined. The change of these values by the change of polymerization conditions, the concentration of monomer, AlEt3, and the temperature, were studied.
