Perspex (polymethyl methacrylate) electrets [PDF]
The decay of the heterocharge of Perspex thermoelectrets as a function of the applied field intensity was studied. This suggests that the decay of the heterocharge is not continuous but occurs in discontinuous jumps. Such a behavior suggests the formation of polarized aggregates that are superficially similar to Weiss domains, which appear to be ...

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.
