Summary The solubility of a number of salts in poly(vinyl methyl ether) (PVME) was tested, and several gave homogeneous solutions over a range of concentrations. When dissolution of the salts occurred, the glass transition temperature of the mixture tended to rise, reflecting the solvation of the cations by the ether oxygens which also leads to crosslinking. Ionic conductivities (σ/Scm−1) were measured for some of the mixtures but the level at room temperature was low. A rise in σ with increase in temperature was observed reaching 10−4 Scn−1 at 430K for PVME/LiClO4 mixtures at a [Li+]/[O] ratio of 0.25.
