The main objective of this paper is verifying the feasibility of using Raman spectroscopy foronline monitoring of suspension polymerization reactions. Whether the Raman spectra areaffected by the particle size distribution (PSD) is also investigated. It is shown that it is possibleto estimate the evolution of conversion during suspension polymerization from Raman spectracollected with the probe connected to the reactor window with a short acquisition time. Resultsalso indicate that monitoring by Raman spectroscopy may allow identification of abnormalbehavior during suspension polymerization reactions with the formation of unexpected PSD.Furthermore, results suggest that Raman spectroscopy probably has the potential to infer thePSD of suspension polymerizations because the Raman spectrum is affected by the PSD.
