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 …

The morphology of the growing polymer particles is important in olefin polymerisation on
supported catalysts. It has a significant impact on the rate of mass and energy transport, and …

In this study, a mathematical model for the time evolution of molecular weight distribution
(MWD) was developed. This temporal model is based on the well-known Ziegler–Natta …

MgCl2· nEtOH adducts play a major role in the industrial production of polyethylenes. Their
chemical dealcoholation, usually accomplished during the catalyst synthesis step, has had a …

The morphology of particles obtained under different pre-polymerization conditions has
been connected to the stress generation mechanism at the polymer/catalyst interface. A …

A two-dimensional single particle finite element model was used to examine the effects of
particle fragmental pattern on the average molecular weights, polymerization rate and …

The effect of fragmentation rate of a catalyst/polymer particle and diffusivity ratio inside
cracks to fragments on reaction rate and molecular weight distribution are studied. A split …

The gas‐phase ethylene polymerizations with SiO2‐supported Ziegler–Natta (ZN) catalyst at
early moments of reaction is modeled. The experimental data used in this work show that at …

In the field of polymer reactor engineering, accurately modeling the complex kinetics and
mass transfer mechanics of a supported-catalyst reaction is essential for designing efficient …

The olefins polymerization process in a slurry reactor is discussed. The reaction rate
dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer …
