خلاصه مقاله:
Ethylene homopolymers samples produced using a new commercial supported Ti-based Ziegler-Natta catalyst were deconvoluted in to flory molecular weight distributions(MWDS). The method of Soares and Hamielec was used to deconvolute the MWDS. The kinetic analysis showed that thecatalyst contains four populations of active centers. Each population has different formation and deactivation rates, produces polymers of different molecular weights and is differently affected by hydrogen. Using Kissin model, Kinetic parameters for each active center of catalyst werecalculated in this study
