POLY-METHYL METHACRYLATE (PMMA)
PMMA is an uncrystallized polymer whose vitreous transition temperature ranges from 110 up to 135°C, i.e. at ambient temperature it is hard, rigid, and brittle with little elongation. PMMA is hygroscopic and,
Rapid characterization of polymethyl methacrylate (PMMA) storage
A novel technique is presented for the rapid estimation of the master curve of storage modulus of a polymer, using laser Doppler vibrometry, infrared thermography, and high-power ultrasonic excitation.
Influence of UV Radiation on Mechanical Properties of Polymer
If only the temperature range of 20 °C to around 45 °C is analyzed, the storage modulus curve of each radiation condition is parallel, which indicates that, for this specific
