Résumé

Near Infrared spectroscopy is used to control a polymerization reactor in order to produce solution polymers with well-defined molecular weight. A model for the monitoring of both the average polymer molecular weight, and the concentration of monomer in the reactor is developed with the partial least-squares calibration technique applied to the NIR spectra.On the basis of a process model, a nonlinear input- output linearizing geometric approach is then applied to control the polymer molecular weight by manipulating the inlet flow rate of the monomer. The control strategy is then validated on-line during the solution polymerization of acrylic acid in an industrial pilot scale reactor.
