Abstract
Dielectric properties of poly(ethylene glycol adipate) and its blends with silicon dioxide were studied in the microwave frequency range. Both real ep silon' and imaginary epsilon" parts of the complex permittivity depend on t he conformation of polymer macromolecules: these values decrease with incre asing content of gauche conformers in the glycol fragment of the monomer un it of macromolecule.
