Abstract
Disclosed is a novel polyetherdiamine comprising an aminated, alkoxylated 1,2'-hydroxyethyl-2-imidazolidone represented by the formula: ##STR1## where R is H or an alkyl group of from 1 to 16 carbon atoms, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are selected from the group consisting of hydrogen and lower alkyl radicals having about 1 to 4 carbon atoms, and a+b=n, wherein n is a number of from about 2 to 80, prepared by reacting urea or certain carbonates with an aminoalkoxylamine, alkoxylating the product with alkylene oxide to form a polyol which is reductively aminated to form a novel polyetherdiamine containing an imidazolidone (cyclic urea).

A compound of the formula:
- ##STR13## wherein R is H or alkyl having 1 to 16 carbon atoms, R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are selected from the group consisting of hydrogen and lower alkyl having from 1 to 4 carbon atoms, and a+b equals n, a number having a value of from 2 to 80 resulting from the reductive amination of a polyol.
