Sterically hindered ditertiary butyl bridged di(cyclohexylamines)

摘要

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: <IMAGE> 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.
