Dynamics of Microphases Separation During RIM Copolymerization: Some Synchrotron SAXS Experiments

Abstract

Using the high x-ray flux afforded by a synchrotron radiation source, the formation of the polyurethane morphology during fast polymerization by reaction injection molding (RIM) was observed as a function of mold temperature through small angle x-ray scattering measurements. To our knowledge, this represents the first time that the development and growth of microphase separation during the polyurethane RIM process has been reported. Reprints.
