ABSTRACT:
Described are carboxyl-terminated polyetheramides of the formula: ##STR1## where R is a moiety from an alcohol or hydroxy compound having a valence of k; R' is independently hydrogen or lower alkyl from 1 to 4 carbon atoms; R" is independently a straight or branched alkylene or aromatic moiety averaging from about 2 to 36 carbon atoms; x averages from about 2 to 100; z averages from about 20 to about 250; k averages from about 1 to 3; m is 0 or 1; and p is independently 5 to 11. Because the carboxyl-terminated polyetheramides are all carboxyl-terminated, they do not gel. They are expected to have good impact strength as well as differing solubilities depending on the polyetheramine incorporated.
