Crystal Structures of Ziegler–Natta Catalyst Supports
Chemistry – A European Journal, 2011AbstractThe crystal structures of three MgCl2⋅n EtOH complexes with n=1.5, 2.8, and 3.3 have been fully determined. Such complexes are the fundamental precursors for Ziegler–Natta polymerization catalysts used to produce polyolefins on a multimillion‐ton scale worldwide.

Metallocene and Ziegler-Natta Catalysts
2021Fifty years ago, Karl Ziegler and Natta won the Nobel Prize for their discovery of the catalytic polymerization of ethylene and propylene using titanium compounds with aluminum-alkyls as co-catalysts. Polyolefins are constantly growing and are now one of the most important highconsumption polymers. New metallocene/methylaluminoxane (MAO) catalysts have

Accelerating the Research Approach to Ziegler–Natta Catalysts
Industrial & Engineering Chemistry Research, 2016Despite 60 years of history and a stunning success, Ti-based Ziegler–Natta catalysts for the production of isotactic polypropylene remain black-box systems, and progress still relies on trial and error. This represents a limitation in a moment when the most widely used industrial systems, containing phthalates as selective modifiers, need to be ...

Living anionic lithium-ended polymer is transformed into a soluble Ziegler-Natta Ti (III)/Li-based system. The latter exhibits a high efficiency as at least 80% of C-Ti bonds participate in the homo- and co-polymerization of ethylene and propene, leading to vinylicolefinic type block copolymers.

Journal of Catalysis, 1964
Abstract A mechanism for the polymerization of olefins is proposed. An essentially octahedrally coordinated ion of a transition element with empty or nearly empty t2g orbitals carrying in its coordination sphere one alkyl group and having one vacant octahedral position is supposed to be the active center.
