Both systems demonstrated conductivity maxima as a function of salt concentration. PTMG electrolytes had dramatically lower conductivities (max. a -3.6 x 10 -7 Scm for PTMG, max. a -1.45 x I0 -Scm for PEG at room temperature) which can be explained on the basis of spectral data which indicate the existence of predominantly neutral species in PTMG. The reason for the difference in the types of species present in PEG and PTMG can be rationalized on the basis of the chelate effect.
