From Cages to Sheets: Computational Elucidation of Methylaluminoxane Structure and Reactivity
ChemPlusChem, Volume 91, Issue 8, August 2026.Methylaluminoxane (MAO), the dominant cocatalyst in metallocene‐based olefin polymerization, has resisted structural characterization for decades. This review traces the computational journey from early cage and nanotube proposals to the identification of two‐dimensional aluminoxane sheets as the thermodynamically preferred motif, and how this ...

Active species in heterogeneous Ziegler-Natta catalysts: "the father of all models"
, 2001 A general model of the catalytic species on the surface of heterogeneous Ziegler-Natta catalysts (either TiCl3-based or MgCl2-supported), based on the statistical analysis of their high-field 13C NMR "fingerprint" in the polymerization products, is ...

Journal of Polymer Science, Volume 64, Issue 14, Page 3057-3072, 15 July 2026.This research elucidates the relationship between the molecular structure of commercially available ethylene–propylene copolymers and an ethylene/1‐olefin copolymer and its ability to compatibilize high‐density polyethylene/isotactic polypropylene blends. These findings indicate that the compatibilization of these blends with random copolymers benefits
