An objective function to determine the optimal operating conditions to produce polymers with a specified molecular weight distribution (MWD) in a continuous stirred tank reactor (CSTR) was formulated. Two polymerization cases were studied: free radical styrene polymerization and cationic isobutylvinylether polymerization. The optimization results of objective function <I>J</I><SUB>1</SUB> in view of finite weight fraction stopped near a curve that passes through a predefined optimal point instead of the target point for both cases. Objective function <I>J</I><SUB>2</SUB>, based on two MWD parameters, was formulated to investigate the optimization result of <I>J</I><SUB>1</SUB>. In the case of styrene polymerization, the optimization searches of <I>J</I><SUB>2</SUB> converged on the optimal point. On the other hand, in the case of isobutylvinylether polymerization, the optimal point cannot be obtained by minimizing <I>J</I><SUB>2</SUB>. In this case, an additional constraint such as polymer concentration is needed to determine an optimal solution.
