Dielectric and spectral characteristics of some aromatic polyether films and tablets

The authors study a series of polyethers and polyesters based on chloromethyl oxetane embedded in polymer matrices of polymethyl metacrylate (PMMA) and polyvinyl alcohol (PVA) type. These polymers have been studied both in solid state as thin films deposed on quartz disks and in solution. The electronic absorption spectra and photochromic effects in such materials are discussed and the polarisation current density is measured.
