The Optimal Profile of Temperature in the Radicalic Polymerization through Methyl Metacrilate


Abstract:
The main purposes of this article are: 1) the minimization of an objective multi-criterial function which implies the reaction time, the polidispersion coefficient and the monomer conversion; 2) the obtaining of reaction conditions (temperature and initiator concentration) which determine the realisation of some final imposed values for conversion and polymerization degree. Within the optimization algorythm there were successively considered as decision variables: 1) a single value of temperature (the isothermal case) and the initiator concentration; 2) two temperature levels and the initiator concentration; 3) thee temperature levels. Of the three optimization strategies, the right one was proved to be the temperature trajectory constituted of two values. The obtained optimal politics essentially depend on the objectively chosen function and on the weight factors attached to each interest measure.
