PACS numbers: 61.05.cp, 78.30.Jw, 81.05.Lg, 81.05.Qk, 81.07.Pr, 82.35.Np, 82.80.Gk

The structure of amorphous polymer systems based on aliphatic epoxy oligomers and lithium perchlorate salt is studied by methods of IR spectroscopy and wide-angle x-ray scattering. It is established the coordinating interaction between lithium cations and ether oxygen atoms of polymer chains. Gradual increasing of the LiClO4 salt content in a volume of epoxy resin leads to displacement of the amorphous halo at 2theta_m = 20.0 degrees characterizing both the short-range order of fragments of the DEG-1 internodal molecular segments and the decrease of the Bragg distance between molecular segments.

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