Gelling and curing behaviors of benzoxazine/epoxy formulations containing 4,4′-thiodiphenol accelerator

▸ Gelling and curing behaviors of benzoxazine/epoxy with accelerator were studied. ▸ The activation energy of gelling was assessed by Arrhenius equation. ▸ The activation energy of curing was determined from dynamic DSC scans. ▸ 4,4′-Thiodiphenol can act as co-reactive accelerator for benzoxazine/epoxy blends. ▸ 4,4′-Thiodiphenol markedly reduced the gel time and the activation energy.
