In the industry of petrochemicals, oligomerization of α-olefins, mainly ethylene and
propylene, is an important process that produces linear α-olefins (LAOs). Industrial …

This short review summarizes the main results achieved in the field of operando
spectroscopies applied to heterogeneous catalysts for olefin polymerization. Following a …

The diverse properties and applications of polyethylenes depend on their molecular
weights, molecular weight distributions, and chain topology. Considering the importance of …

As part of a continuing effort to better understand the initiation (ie, the reduction and self-
alkylation) of the Phillips commercial Cr (VI)/silica catalyst, this study attempted to …

Mesoporous silica is a versatile material for energy, environmental, and medical
applications. Here, for the first time, we report a flame aerosol synthesis method for a class of …

Kinetics-based differences in the early stage fragmentation of two structurally analogous
silica-supported hafnocene-and zirconocene-based catalysts were observed during gas …

In this work, supported organochromium ethylene polymerization catalysts have been tuned
to mediate ethylene oligomerization via surface lithiation, which provides a generalizable …

Heterogeneous organochromium catalysts have been developed via surface lithiation of
traditional surface organometallic complexes to mediate stereoselective isoprene …

Chromium complexes bearing non-innocent iminopyridine ligands were investigated as
precatalysts for the polymerization of ethylene using different aluminum cocatalysts and …

Abstract Bistriphenylsilyl chromate (BC)/silica (S‐2 catalyst) is a commercially used high‐
density polyethylene (HDPE) catalyst with great importance. In this work, the catalytic …
