Transition-metal complexes are attractive targets for the design of catalysts and functional
materials. The behavior of the metal–organic bond, while very tunable for achieving target …

Abstract 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 …

Organometallic chemistry has provided the foundation for the development of a wide range
of new olefin polymerization catalysts over the last two to three decades. The unraveling of …

Although Ziegler–Natta (ZN) catalysts play a major role in the polyolefin market, a true
understanding of their properties at the molecular level is still missing. In particular, there is a …

One catalyst, many materials: The chemistry of polyolefins has been thoroughly explored,
and it sometimes seems as if any given polymer structure can be obtained by derivatization …

This study focuses on building enantioselectivity models using only a few intuitively
meaningful descriptors based on the “buried volume” idea. Appropriate dissection of the …

Olefin polymerization catalyzed by Group 4 transition metals is studied here as test case to
reveal the entropy effects when bimolecular and unimolecular reactions are computed for …

Stiffening of the catalyst backbone of salan-type catalyst 1via ring closure yields
indanosalan 3 and increases activity and molar mass capability by two orders of magnitude …

Homogeneous single-site alkene polymerization is a “mature” field. However, this does not
imply that interest to this research area fades. Moreover, armed by well understood …

Isotactic polypropylene (iPP) is a thermoplastic material of vast importance. The ever-
increasing demand for it is derived from its useful physical properties and the availability of …
