Abstract
The aim of this research is to develop a mathematical model for the propylene polymerization batch reactor for a local petrochemical company. The kinetics of polymerization is based on a single type of active sites on Ziegler–Natta catalyst. The model is composed of a number of algebraic and stiff ordinary differential equations which are solved simultaneously using MATLAB script language. The developed model was used to predict the properties of end-product, which include weight and number average molecular weight, polydispersity index (PDI) and melt flow index (MFI). The simulated batch runs were validated against real batch runs for the values of melt flow index. An average absolute error of 10.8 % was achieved.
