Ethoxy ethanol conductivity

Although MEEP-metal salt complexes show high ionic conductivities, these materials have undesirable creep properties at ambient temperatures, thus precluding their use in practical devices. To overcome this problem, one approach has been to synthesize dimensionally stable poly(phosphazenes) by crosslinking poly-[(chloro)(methoxy ethoxy ethoxy) phosphazene] with polyethylene glycol). If some of the chlorines in poly(dichlorophosphazene) are left unsubstituted after the initial reaction with the sodium salt of methoxy ethoxy ethanol, these can be reacted further with the difunctional poly(ethylene glycol)to afford crosslinked materials (Eq. 13 and Scheme 14) [204]...
