Аннотация:A series of novel anionic block copolymers, in which the neutral block is formed by 2-phenylethylmethacrylate (PEM) and the ionic block is prepared via statistical copolymerization of lithium 1-[3-(methacryloyloxy)-propylsulfonyl]-1-(trifluoromethanesulfonyl)imide (LiM) and methyl ether of poly(ethyleneglycol) methacrylate (PEGM) have been synthesized. The effects of chemical structure, composition, andmolecular mass of the blocks on ionic conductivity and thermal properties of the poly[PEM–block–(LiM–stat–PEGM)] block copolymers have been investigated. It has been found by means of small-angle X-rayscattering that the introduction of a small fraction of the lithium-containing units (~7 mol %) in the structureof neutral poly[PEM–block–PEGM] copolymer leads to microphase separation and ordering of the system.Combined small-angle X-ray scattering and atomic force microscopy data have evidenced the formation oflamellar structure with the interplanar distance of d ~ 28 nm.
