Abstract: Abstract The dielectric relaxation of unsaturated polyester resin during cure was modeled using a modified Williams–Watts decay function. The dielectric response was studied using dielectric measurements coupled with two dynamic mechanical measurement methods. It was found that the variation of the relaxation time during cure is a WLF process using Tg (α) (α‐conversion) as the varied temperature. It was shown that this process fits the Williams‐Watts decay function Φ(t)=exp(‐(t/τ)β) where τ‐relaxation time an…
