N2 - The effects of hydrodynamic boundary layer mass transfer, methylaluminoxane anion design, and comonomer steric hindrance - on non-Z-N-catalyzed ethylene polymerization were studied. These variables significantly influenced catalyst productivity and copolymer microstructure, which eventually influenced the resulting polyethylene thermal behavior (melting and crystallization). The comonomer-induced structural/enchainment defects and the eventual partial disruption of the crystal package of the polyethylene chains were successfully modeled using Flory and Gibbs-Thompson equations. The models, combined with experiments, generated insightful new results. This is an abstract of a paper presented at the 25th Annual Saudi-Japan Symposium on Catalysts in Petroleum Refining and Petrochemicals 2015 (Dhahran, Saudi Arabia 12/7-8/2015).
