Abstract
Dielectric properties of poly(ethylene glycol adipate)-graphite compos itions were studied in the microwave frequency range. The concentratio n and temperature dependences of the complex permittivity are obtained for various temperatures of the sample preparation. The dielectric pr operties in the subcritical concentration range depend on the macromol ecular conformations: an increase in the content of trans conformers i n the glycol segment of the monomer unit increases both real and imagi nary parts of the permittivity of the polymer-graphite composition.
