An immersion Raman probe was used in emulsion copolymerization reactions to measure monomer concentrations and particle size. Quantitative determination of monomer concentrations is feasible in two-monomer co-polymerizations, but only the overall conversion could be measured by Raman spectroscopy in a four-monomer co-polymerization. Feasibility of measuring monomer conversion and particle size was established using partial least square (PLS) calibration models. A simplified theoretical framework for measurement of particle sizes based on photon scattering is presented, based on the elastic sphere vibration and surface tension models.
