Single particle modelling for olefin polymerization on supported catalysts: A review and proposals for future developments
In the present article, we review the state-of-the-art models for single particle olefin polymerization models. Special attention is paid to particle growth, polymerization rates, concentration and temperature radial profiles, polymer microstructure, and particle morphology. It is proposed that these models can be conveniently classified as polymer property and particle morphology models, according to their most important predictive abilities, even though particle morphology characteristics will influence polymer properties and vice versa. Currently, there is no single model that incorporates all of these modelling aspects into a unified formulation. A great deal of progress has been made toward understanding the relationship between the important phenomena involved in modelling single particle growth. It seems that the basic understanding on modelling polymer proper-ties is quite substantial, but there is still significant contributions to be made when modelling the morphology evolution of these complex polymer particles. Some of these areas are discussed and suggestions for future development are made.
