Aromatic polyimide films were prepared and their dielectric constant and relaxation behavior were studied. Polyimide films have good insulating properties with dielectric constant values in the range of 2.88 – 3.48 at 1Hz and room temperature. Three relaxation processes (γ, β 1 and β 2 ) at sub-glass temperatures were observed and investigated. The cooperativity of the molecular motions associated with the relaxation processes was discussed.
