Dynamic mechanical thermal analysis of dental polymers

Add time:08/06/2019    Source:sciencedirect.com

Four heterocyclic methacrylates were investigated with respect to their loss tangent and activation energy using a dynamic mechanical thermal analyser over a limited frequency range of 0.033 to 90 Hz. The linear regression lines obtained showed an Arrhenius-type relationship between transition temperature and frequency. Their low activation energies in comparison to poly (methyl methacrylate) and bis-phenol A based methacrylates was thought to be a direct consequence of their low molecular weights.
