TL;DR: In this article, the formation of either fibers or micrometer-sized polymers is presented, where the morphologies and properties of polymers are pivotal for their manufacturing and processing at the industrial scale.

TL;DR: It is shown that there is a strong heterogeneity in the overall catalyst particle fragmentation and thus polymerization activity within the entire ensemble, which hints toward local mass transfer limitations or other deactivation phenomena.

TL;DR: This work combines X-ray diffraction and spectroscopy to probe each step of the birth and life of a MgCl2 -based Ziegler-Natta catalyst, namely the formation of high surface area M gCl2 by dealcoholation of an alcoholate precursor, the TiCl4 grafting, and the subsequent activation by triethylaluminum as co-catalyst.

TL;DR: It is shown that by varying the type and amount of metal‐alkyl co‐catalyst, one can tailor polymer properties around a single Cr/SiO2 Phillips catalyst formulation, and that these different polymer properties exist in the early stages of polymerization.

TL;DR: In this article, the authors investigated the catalytic properties of metal-organic frameworks (MOFs) for polyethylene (PE) polymerization and showed that the PE polymerization occurs over a multitude of active Cr centers rather than a singular type of Cr sites.
