| Abstract | A renewable bisepoxide, SYR-EPO, was prepared from syringaresinol, a naturally occurring bisphenol deriving from sinapic acid, by using a chemo-enzymatic synthetic pathway. Estrogenic activity tests revealed no endocrine disruption for syringaresinol. Its glycidylation afforded SYR-EPO with excellent yield and purity. This biobased, safe epoxy precursor was then cured with conventional and renewable diamines for the preparation of epoxy-amine resins. The resulting thermosets were thermally and mechanically characterized. Thermal analyses of these new resins showed excellent thermal stabilities (Td5?% =279-309?°C) and Tg ranging from 73 to 126?°C, almost reaching the properties of those obtained with the diglycidylether of bisphenol?A (DGEBA), extensively used in the polymer industry (Td5?% =319?°C and Tg =150?°C for DGEBA/isophorone diamine resins). Degradation studies in NaOH and HCl aqueous solutions also highlighted the robustness of the syringaresinol-based resins, similar to bisphenol?A (BPA). All these results undoubtedly confirmed the potential of syringaresinol as a greener and safer substitute for BPA. |
