Abstract

We describe measurements of particle size during the course of a latex emulsion polymerization reaction using fiber optic dynamic light scattering (FODLS). These measurements are compared to results from dynamic light scattering (DLS) measurements performed in the usual way on diluted samples. It is shown that the FODLS measurements follow the DLS results and reliably track the growth of the latex particles throughout the reaction. It thus appears that the FODLS technique is useful for the measurement of particle size in highly concentrated samples, such as is found in latex production.
