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

open access: yes, 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 ...

Computational Modeling of Heterogeneous Ziegler-Natta Catalysts for Olefins Polymerization

open access: yesProgress in Polymer Science, 2018
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 ...
