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 …

Heterogeneous catalysis for olefin polymerization is one of the most relevant industrial
processes in terms of worldwide diffusion, material volume, and economic turnover. At the …

Although the formation of nanosized and defective δ-MgCl2 is essential for the performance
of Ziegler–Natta catalysts, the process has not sufficiently been elucidated due to certain …

MgCl2 supported Ziegler–Natta (Z–N) catalysts have emerged as the most exciting chemical
process for polyolefin technology, which is responsible for the production of∼ 150 million …

Rapid developments in materials engineering are accompanied by the equally rapid
development of new technologies, which are now increasingly used in various branches of …

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

Absolute rigidity is rare in the “soft” world of organometallics. Here we introduce two
cyclopenta [a] triptycyl ansa-zirconocene catalysts for isotactic-selective propene …

Linear polyethylene and isotactic polypropylene, the two largest-volume polymers on the
market, were invented in the 1950s thanks to diverse mixes of serendipity, intuition and …

Catalytic activity in olefin polymerization depends not only on the catalyst but also, crucially,
on activator/alkylator/scavenger “packages.” Along with binary mixtures containing Lewis or …

Statistical olefin block copolymers (OBCs) with “hard” and “soft” linear low-density
polyethylene (LLDPE) blocks can be synthesized by tandem catalysis under “coordinative …
