The molecular weight distribution (MWD) is possibly the most important characteristic of a
polymer. Polymers derive many of their physical properties from their MWD. Therefore, since …

Slurry polymerization processes using Zeigler–Natta catalysts, are most widely used for the
production of polyethylene due to their several advantages over other processes. Significant …

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 …

The multigrain model (MGM) is the most widely used single-particle model, giving a detailed
description of phenomena during olefin polymerization. However, the detailed modeling of …

This work aims to perform steady-state and dynamic modeling of an industrial solution
polyethylene process. The phase behaviors in reactors under various conditions were …

A hierarchical and computationally efficient mathematical model was developed to explain
the polymerization of high-density polyethylene (HDPE) in an isothermal, industrial …

This work aims on develo** a novel process that is applicable to solution and slurry
polymerization, which can efficiently control production efficiency, product properties and …

A multiscale model of slurry-phase olefin polymerization is developed by extending the
multigrain model to account for the existence of gas–liquid mass transfer resistance in an …

New bimodal high-density polyethylene (HDPE) resins are commonly developed in pilot
plants. Among multiple goals, the tests aim to determine the operational conditions of the …

The alteration of the molecular weight distribution (MWD) in high-density polyethylenes
(HDPEs) can effectively address processing challenges. However, widening the MWD may …
