Research on “post‐metallocene” polymerization catalysis ranges methodologically from
fundamental mechanistic studies of polymerization reactions over catalyst design to material …

This paper reports the principal discoveries which have played a major role in the polyolefin
field and have positioned polyolefins as the most produced plastics. The early development …

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 …

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 …

Catalyzed by the (pyridylamido) hafnium/organoboron system, a series of halogen-
functionalized isotactic polypropylenes were synthesized via the stereospecific …

UV irradiation of latent sulfur-chelated ruthenium olefin metathesis precatalysts produced a
cis-dichloro− trans-dichloro photoisomerization. The enhanced activity of the trans isomer …

A detailed study of the effect of reaction temperature, time, and cocatalyst composition on the
ethylene polymerization performance of 2-[1-(2, 6-dibenzhydryl-4-chlorophenylimino) ethyl] …

Chromophore quench-labeling applied to 1-octene polymerization as catalyzed by hafnium-
pyridyl amido precursors enables quantification of the amount of active catalyst and …

Stereoselective propene polymerization mechanisms promoted by C 1-symmetric transition
metal (TM) catalysts with nonmetallocene and ansa-metallocene ligands have been …

d0 metal-alkyl complexes (M= Ti, Zr, and Hf) show specific activity and selectivity in olefin
polymerization and oligomerization depending on their ligand set and charge. Here, we …
