The Decay of Irradiation Defects in Dyed Polymethyl Methacrylate [PDF]
The decay of defects in polymethyl methacrylate caused by γ-irradiation has been followed by electron-spin resonance. The samples were irradiated at room temperature and annealed at 80, 90, and 100 C. Two radical species can be recognized by their different modes of decay.

Radiochemical “degelation” of polymethyl methacrylate networks [PDF]
Methyl methacrylate-ethylene glycol dimethacrylate networks were synthetized and submitted to radiochemical degradation, with ageing monitored by means of sol-gel analysis. The networks were shown to undergo chain scission predominantly, which leads to their degelation, i.e., the recovery of a thermoplastic-like behavior with loss of all elastically ...

Fracture of Polymethyl Methacrylate
Polymethyl methacrylate specimens were fractured by the static bending, and the speed of the crack propagation was measured by the speed of breaking of the electro-conductive coatings on the surface of the specimens. The rate of crack propagation speed obtained by our method is found to be greater than that which has been obtained by any other ...

Gamma irradiation effects on polymethyl methacrylate
AbstractThe effect of gamma‐irradiation on the structure of polymethyl methacrylate (PMMA) has been investigated. In this study, the PMMA specimens were gamma‐irradiated at doses in the range of 0‐1000 kGy and measured by means of positron annihilation lifetime (PAL) spectroscopy.
