Abstract

Changes in microviscosity during polymerization of vinyltoluene have been studied using fluorescence polarization and intensity measurements. A variety of fluorescence probes were employed. "The" microviscosity of the polymerizing medium experienced by a fluorescent probe is dependent upon the size of the kinetic unit responsible for the variation in observed emission characteristic. No stepwise increments in microviscosity upon conversion to polymer were recorded in any of the systems studied.
