Abstract
This invention relates to ditertiary-butyl substituted bridged di(cyclohexylamines) where the tert-butyl substituent is alpha to the amine group and to polyepoxide formulations incorporating the di(cyclohexylamine). The formula of the diamine is: ##STR1## wherein R is tert-butyl. The di(tertiary butyl)methylene bridged cyclohexylamines have delayed reactivity when incorporated in epoxy resins and they also enhance physical properties in high resilience polyurethane foams.
