The free volume of a bisphenol-A-type epoxide oligomer (DGEBA) was studied using Williams–Landel–Ferry parameters and thermal expansion coefficients above and below the glass transition temperature (Tg). The values of the free-volume fraction at

Dielectric properties above the glass transition temperature (T g ) have been investigated for three bisphenol-A novolac type epoxide oligomers (PGEBANs) that have some branching in each molecule in comparison with the diglycidyl ether of bisphenol-A
