Abstract

The association of kinetic studies, DFT calculations and ¹H–⁷Li NMR analyses allowed the control of the cyclo-ATRP of PEG₉DMA and the production of polymethacrylate pseudo crown-ethers of various molar masses. Their potential to act as a solid-state polymer electrolyte in Li-ion batteries has been highlighted and may come from the supramolecular organization of the cyclo-PEG forming a Li⁺ diffusion channel.
