Comparison of Photo- and EB-Initiated Polymerizations Based on Equivalent Initiation Energy

Abstract:In this study, a protocol was developed to investigate photo- and EB-polymerized films of equivalent initiation energies. This protocol was then applied to a series of monomers to characterize the impact of the initiation mechanism on energy rate effects. Raman spectroscopy and dynamic mechanical analysis were used to determine differences in polymer conversion and physical properties, respectively. Monomer chemistry was shown to be a key variable in the comparison of the two initiation mechanisms.
