Synthesis of a Sustainable and Bisphenol A‐Free Epoxy Resin Based on Sorbic Acid and Characterization of the Cured Thermoset

In the present study, an epoxy compound, 1,2-epoxy-6-methyl-triglycidyl-3,4,5-cyclohexanetricarboxylate (EGCHC) synthesized from sorbic acid, maleic anhydride, and allyl alcohol is proposed. Using commodity chemicals, a bio-based carbon content of 68.4 % for EGCHC resin achieved. When cured with amine hardeners, high oxirane forms stiff cross-linked networks strong mechanical thermal properties. The characterization specimens showed that can compete conventional resins such as DGEBA. A maximum stiffness 3965 MPa, tensile strength 76 Tg 130 °C be obtained by curing isophorone diamine (IPD). to decomposable under mild conditions due ester bonds. solid material properties expose its potential promising bisphenol A, epichlorohydrine free alternative petroleum-based epoxies overall content.
