The main disadvantage with pre-determined recipe is that the poor control of molecular weight distribution may arise due to process disturbances. The question is then how to mod-ify the pre-determined recipe in the presence of disturbances. In this study, therefore, we develop the on-line two-step method to obtain the polymer product with the desired MWD under process disturbances. As an illustrative example of the on-line two step method, we use the solution polymerization model for styrene in a batch reactor system and discuss the implementation issues for the on-line two-step method.
