Abstract
Amines endowed with chain extension activity for formulations such as polyureas and polyurethanes are disclosed, which have the general formula: ##STR1## wherein n is 1-1000 and m is 1-100; R.sub.1 and R.sub.2 are from the group --C.sub.2 H.sub.4 -- and C.sub.3 H.sub.6 --; and R.sub.3 and R.sub.4 are each independently selected from the group consisting of H, --CH.sub.3, --CH.sub.2 CH.sub.3, --CH.sub.2 OH, and --CH.sub.2 --CH.sub.2 --OH; and the diasteromeric salts thereof.
