Abstract
This invention relates to bridged cyclohexylamines represented by the formula: ##STR1## A is C.sub.0, --CH.sub.2 --, ##STR2## R.sub.1 is C.sub.1-3 alkyl R.sub.2 is C.sub.1-6 alkyl PA0 R.sub.3 is C.sub.1 or C.sub.2 alkyl PA0 R.sub.4 is H or C.sub.1-4 alkyl PA0 x is 0 or 1 PA0 y is 0 or 1 These bridged bis(cyclohexylamine) derivatives are well suited as curing agents for epoxy resins. These compositions lead to enhanced processing of the epoxy resin and permit adjustment of the reactivity/performance in formulating epoxies which demonstrate superior high temperature properties.
