Multi-frequency dynamic-mechanical thermal analysis of methyl methacrylate adhesive (MMA)

Abstract

The paper presents the results of Dynamic-Mechanical Thermal Analysis (DMTA) for a selected methacrylate adhesive at the frequency range from 1 to 50 Hz and the heating rate of 1 and 3 °C/min, in the range from –70 °C to 180 °C. On the basis of the test results, the glass transition temperature was evaluated for three calculation methods. Master curves were also designated for three different reference temperatures: –20, +20 and +60 °C. Master curves were calculated using shift factors aT - calculated by numerical method.
