SENSORS: In-Line Monitoring of Particle Size during Emulsion Polymerization under Different Operational Conditions using NIR Spectroscopy

SENSORS: In-Line Monitoring of Particle Size during Emulsion Polymerization under Different Operational Conditions using NIR Spectroscopy

Dennis L. Chicoma, Claudia Sayer, Reinaldo Giudici*

Effects of light scattering by polymer particles affects some spectral regions of the NIR spectra collected in-line during emulsion polymerization. Appropriate calibration models can be obtained to relate the NIR spectra with the values of the average particle size (measured off-line by DLS), thus allowing the online monitoring of particle size during the polymerization.
