Optimal processing conditions of a bio-based epoxy synthesized from vanillyl alcohol

This work provides a comprehensive thermomechanical and rheological characterization of a high-performance epoxy resin synthesized from a vanillin derivative, vanillyl alcohol. The study includes a complete analysis of the curing and decomposition kinetics that enabled a Time-Temperature-Transformat...
