Abstract
Cured epoxy resins are widespread because of their excellent mechanical and chemical properties. Typically, epoxy resins based on bisphenol A diglycidyl ethers or bisphenol F diglycidyl ethers are used, but these are problematic for many sectors because of their effect on the endocrine system. The present invention relates to glycidyl ethers of limonene-based diols and/or polyols, and to curable epoxy resin compositions based thereon as alternatives to the bisphenol A diglycidyl ethers or bisphenol F diglycidyl ethers, or the epoxy resin compositions based thereon.
