Synthesis of novel non-glycidyl ether epoxy resins via the Corey–Chaykovsky reaction and preparation of high heat-resistant cured products by their curing reaction

Non-glycidyl ether epoxy resins were synthesized via the Corey–Chaykovsky reaction and cured to afford cured products with high heat resistance. Among them, the cured product prepared from spiro-structured DBO exhibited the best performance.
