37. EX in these melts may represent a contact reaction. The equilibrium δ is however, the appropriate distance to represent the overall diffusive charge displacement. δ is calculated based on a cubic lattice model. Density ρ, metal complex concentration C, and center-to-center metal spacing δ for 2 are ρ = 1.12 g/cm3, C = 0.327 M, and δ = 17.2 Å. respectively.
38. Polyether segmental motions however, do not seem to be affected. DSC provides identical glassing temperatures of -52.4 °C for all of the materials studied here. This glassing temperature is characteristic of ethylene oxide, but is surprising given the obvious differences in rigidity of the materials. They range from a soft plastic like material for 2 to a viscous liquid for 1.
39. 2 increases, illustrates the role of diffusion in affecting the observed current changes of Figure 3.
