A kinetic model for industrial gas-phase ethylene copolymerization

A dynamic kinetic model describing gas‐phase olefin copolymerization using a multiple active site Ziegler‐Natta catalyst is presented. This model is capable of predicting production rate, molecular weight, and copolymer composition changes observed in an industrial reactor. The model also explains h...

Description
Summary:A dynamic kinetic model describing gas‐phase olefin copolymerization using a multiple active site Ziegler‐Natta catalyst is presented. This model is capable of predicting production rate, molecular weight, and copolymer composition changes observed in an industrial reactor. The model also explains how broad molecular weight distributions and bimodal copolymer compositions can occur as has been observed for commercial linear polyethylenes.
