Active species in heterogeneous Ziegler-Natta catalysts: "the father of all models"
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 ...

Computational Modeling of Heterogeneous Ziegler-Natta Catalysts for Olefins Polymerization
Since 1963, when Karl Ziegler and Giulio Natta were jointly awarded the Nobel Prize for their discoveries of the catalytic polymerization of olefins with Ti-chlorides and Al-alkyls, heterogeneous Ziegler-Natta (ZN) catalysts have become the main ...

Transition Metal Imido Compounds as Ziegler–Natta Olefin Polymerisation Catalysts
Transition metal imido compounds having the general formula [(L) nM(NR)] [where (L) n is a supporting ligand or ligand set, and R typically is alkyl or aryl] have been known for nearly 50 years, and ...
