Abstract

A detailed dynamic model has been developed for the molecular weight distribution (MWD) of styrene bulk polymerization in a continuous stirred tank reactor (CSTR). The moment techniques are applied to formulate the MWD parameters based on the Schultz-Zimm distribution. In order to provide a general model for MWD control, the B-spline approximation has been introduced into the dynamic MWD modelling and the scanning least-square algorithm has been used for parameter estimation of the B-spline weights model. Under simulation environment, this model has been proved to be efficient for feedback MWD control.
