PACS numbers: 61.05.cf, 61.05.cp, 61.41.+e, 78.30.Jw, 81.05.Lg, 81.07.Pr, 82.35.Lr, 82.80.Gk

A structure of amorphous polymer systems based on aliphatic epoxy oligomers and lithium perchlorate salt are studied by methods of IR spectroscopy and wide-angle X-ray scattering. As established, there is a coordinating interaction between lithium cations and ether oxygen atoms of polymer chains. Gradual increasing of the salt LiClO4 content within the bulk of epoxy resin leads to a displacement of the amorphous halo at $2\theta_{m}$ = $20^{\circ}$ to wide-angle scattering range that characterizes both the short-range order of fragments of the DEG-1 interstitial molecular segments and the decrease of the Bragg distance between these molecular segments.

Key words: polymer, amorphous system, structure, complexes, ion–dipole interaction.
