The field of olefin polymerization catalysis has experienced a phenomenal acceleration in
research activity over the past 5 years, with many academic and industrial research …

Staudinger predicted a correlation between the physical properties of a polymer and its main-
chain stereochemistry as early as 1929. 1 However it was not until 1947 that Schildknecht …

Detailed investigations of the polymerization of ethylene by (α-diimine) nickel (II) catalysts
are reported. Effects of structural variations of the diimine ligand on catalyst activities …

50 years ago, Karl Ziegler and Giulio Natta were awarded the Nobel Prize for their discovery
of the catalytic polymerization of ethylene and propylene using titanium compounds and …

Coordination–insertion polymerization systems have long been superior to their anionic,
cationic, and radical polymerization counterparts with regard to stereochemical control …

A series of bis (imino) pyridyliron and‐cobalt complexes [{2, 6‐(CR= NAr) 2C5H3N}
MX2](R= H, Me; M Fe, Co; X= Cl, Br) 8‐16 containing imino‐aryl rings (Ar) with at least one …

Cationic complexes of late transition metals with multidentate ligands have recently been
found to catalyze various novel homo-and copolymerization reactions of olefins. In this …

The propylene polymerization behavior of a series of Ti complexes featuring fluorine-
containing phenoxy− imine chelate ligands is reported. The Ti complexes combined with …

Recent progress on nickel-based complex pre-catalysts has been reviewed. Variation of the
complex models by employing different types of heteroatom-containing ligands and the new …

After the discovery of single center metallocene catalysts in the 1980s highly stereoregular
syndiotactic polypropylene showing high crystallinity and melting temperature has been …
