Synthesis and Characterization of Homogeneous Epoxy Networks: Development of a Sustainable Material Platform Using Epoxy-Alcohol Polyaddition

The development of bio-based epoxy resins from aliphatic biomass and lignin has rapidly increased over the past few decades. While thermal curing such monomers with polyfunctional amines anhydrides been intensively discussed in literature, surprisingly, their polymerization behavior using alcohols as co-curing agents resulting mechanical properties have not investigated detail up to now. Herein, mode epoxides imidazoles catalysts was studied via1H-NMR analysis, revealing a controlled alternating co-polymerization between difunctional alcohol monomers. Furthermore, differential scanning calorimetry analysis used obtain theoretical heat (∼100 kJ mol–1) multifunctional formulations exhibited high storage stabilities 28 days. By varying core structure functionality monomers, high-performance thermosets tunable TG (0–110 °C) tensile toughness 18 MJ m–3 were obtained. These performances show potential for application networks coatings key industrial sections automotive technologies.
