Pressure‐Decay Kinetic Modeling of Homogeneous Ethylene Polymerization with Et(Ind)2ZrCl2/TIBA‐Borate Catalyst System in a Batch Reactor

Polymer Engineering &Science, EarlyView.
A kinetic model comprising both propagation and deactivation functions was developed for metallocene‐catalyzed ethylene polymerization in a batch reactor. The model predicted polymer yields very close to the experimental ones. The polymer molecular weight increased with ethylene pressure and decreased with temperature.
