Abstract

A model is proposed to estimate the dosage rate of monomers in a polymerization reaction. The model consists of a bimodal Gamma probability distribution function for describing the conversion velocity of monomers in a flask polymerization reaction (laboratory scale). The function of conversion percentage of monomers (the integral of the conversion velocity of monomers) is correlated with the experimental data. From this function, the conversion percentage of monomers is developed for a polymerization reaction, where monomers are added with a suitable dosage rate. The dosage rate of monomers is determined from a minimization procedure applied to the mean square deviation between the conversion percentage of the fast and slow monomers. In this way, the dosage rate of monomers is estimated to define the polymerization experiment on micro-plant scale. From these experiments, the resulting polymeric product (with 1 L or 5 L scale) is homogeneous and without residual monomers.


Keywords
