A study of photo- and thermo-initiated polymerised dimethacrylates by three thermal analysis techniques. Havard, N., Dargent, E., Lebaudy, P., Lecamp, L., & Grenet, J. Journal of Thermal Analysis and Calorimetry, 61(3):701–709, 2000. doi abstract bibtex Photo-initiated polymerisation of dimethacrylate oligomers provide an easy method for producing highly crosslinked polymer networks. The physical properties of the material are dependent on the polymerisation conversion value. The determination of this conversion value is quite difficult on the final product. The first step is to measure a characteristic temperature of the glass transition. The weakness of the DSC glass transition signal makes this measure unrealisable while the DMA tan peak is broad and weak. At the difference of these two thermal analysis techniques, TSDC gives an observable signal and a T-alpha temperature close to the glass transition temperature region. The bad sample preparation reproducibility observed was attributed to the high conversion rate.
