Abstract
Poly-(2-aminoalkyl)polyamine compounds are provided having the following formula: ##STR1## wherein: n is an integer of from 2 to about 12; R.sub.1 is selected from H and an alkyl group containing from 1 to about 10 carbon atoms; R.sub.2 and R.sub.3 are each independently selected from H and a lower alkyl group containing from 1 to about 6 carbon atoms; R.sub.4 is selected from H and ##STR2## and R.sub.5 is selected from an amine terminated polyol moiety having a molecular weight of from about 150 to about 5,000, from about 2 to about 80 ether linkages, and a valence of from about 2 to about 12.
