Tracking Offline Conversion Solution Polymerization of Methyl Methacrylate / Vinyl Acetate in Toluene in a Reactor Calorimeter

Analyses systems by chromatography in gaseous phase and by gravimetric have been used for the offline follow-up of the conversion of monomers during the copolymerization in solution of methyl methacrylate (MMA) and vinyl acetate (AVc) conducted in the calorimetric reactor (batch). In the present work, an empirical model was generated using of the calibration curve connecting the spectral data CPG to the measured conversion by gravimetric. The obtained calibration was characterized by a correlation coefficient of 99.57%. The rate of conversion of MMA (83%) is higher compared to AVc (26%) according to the rate of reactivity (rMMA = 26 and rAVc = 0.0319). The results obtained by gravimetric and CPG are well adapted for the follow-up of the polymerization reaction.
