Alkali‐metal salts of (ω‐carboxy)oligo(oxyethylene) methacrylate (CME 12 M, M = Li or Cs) have been synthesized and polymerized to prepare solid polymer electrolytes. These types of solid polymer electgrolytes provide a homogeneous phase, since these polymers have a flexible main chain, an oligo(oxyethylene) side chain for ion conduction, and a carrier ion source in one repeating unit. The AC conductivity of P(CME 12 Li) homopolymer is 8.9 × 10 −9 S cm −1 at 30°C, while that of P(CME 12 Cs) is 3.3 × 10 −6 S cm −1 at 30°C, which is the highest value among single ion conductors, have been reported as polyelectrolyte “homopolymer” without any additives. High ionic conduction of P(CME 12 Cs) is due to low glass transition temperature (T g = −54°C) and weaker ion–ion and ion–dipole interaction of Cs + than that of Li + .
