PEO structure models. (a) A general polyethylene oxide backbone. While the persistent chain (stretched) shows large Kuhn lengths b, the flexible chain (b) (e.g. in solution) shows a higher degree of entanglement with short Kuhn lengths. The ratio of \(R_0\) to \(R_\text {g}\) is \({6^{1/2}}=2.45\) for an ideal chain and therefore close to the diameter to radius ratio from spheres.
