Abstract
Di-amines endowed with chain extension activity for formulations such as polyureas and polyurethanes are disclosed, and which have the general formula: ##STR1## wherein n is 0-1000; R.sub.1, R.sub.2, R.sub.5, and R.sub.6 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; R.sub.3 .dbd.R.sub.4, and R.sub.3 and R.sub.4 are from the group --CH.sub.2 --CH.sub.2 --; --CH.sub.2 --C(CH.sub.3)H--; and --C(CH.sub.3)H--CH.sub.2 --; and the diasteromeric salts thereof.
