This paper presents an experimental kinetic study of the polymerization of propylene in liquid monomer with a high activity catalyst. The influences of the concentration of hydrogen and the molar ratios of the catalyst, cocatalyst, and electron donor on the activation period, the maximum activity, t
Propylene polymerization was investigated with a sequential addition of Ziegler-Natta and metallocene catalysts. From the fact that the molecular weights of polypropylene (PP) produced with Ziegler-Natta and with metallocene catalysts differ, it was possible to control the molecular weight distribut
This study focuses on the kinetics of ethylene/propylene (homo/co)polymerization reactions using a high activity TiCl 4 /MgCl 2 /AlEt 3 catalyst. The reactor system is a gas phase reactor equipped with an on-line composition control scheme. As such, important kinetic data such as the instantaneous r
