In collaboration with the company Coatex, we have used NIR spectroscopy to monitor a polymerisation process pro- ducing water-soluble polymers. The main process parameters to be monitored in this application are the molecular weight distribution and the concentration of monomer in the reac- tor. For this particular application, the quality of the produced polymer is main- ly determined by its molecular weight. The concentration of monomer in the reactor is also an important process parameter in terms of process security and productivity. For these reasons on- line monitoring of the process turns out to be necessary. NIR spectrometry is used to perform the on-line monitoring of the polymeri- sation process. The spectrometer is cal- ibrated using the partial least squares (PLS) calibration technique applied to the NIR spectra
