Abstract
Abstract Aminoalkoxyamides are provided of the formula: ##STR1## wherein R 4 is selected from H and ##STR2## and R 1 , R 2 and R 3 are all independently selected from H or a lower alkyl group having from 1 to about 6 carbon atoms. Also provided are epoxy resin compositions containing such amine-containing compounds as epoxy curing agents and methods for curing epoxy resins where such curing agents may be employed.
