Abstract
An epoxy resin is provided that includes a diglycidyl ether of a substituted cycloaliphatic diol or bis-thiol, and a thermoset epoxy polymer is provided employing the same. The epoxy resin is bisphenol A free, and capable of forming thermoset epoxy polymers with fewer associated health and environmental concerns than conventional epoxies based on phenolic compounds.
