44 Kinetics of Propylene Bulk Polymerization with a Spherical Ziegler-Natta Catalyst

Experiments were carried out in a novel laboratory reactor with an on-line monitor and a control system to study the kinetics of bulk polymerization of propylene in both gas and liquid phases. Flory-Huggins equation was used to estimate the monomer concentration in the amorphous region of the polymer. The time evolution of polymerization rate under all conditions followed the same pattern, with a fast decay in the early stage of the …
