ABSTRACT:
This invention relates to imino dicarboxylic acids (IDA) of the general formulae ##STR1## where Z is a moiety, preferably aromatic, R is a moiety, preferably aliphatic, and to resins derived from such acids. Such resins, which may vary widely, are illustrated by polyesters, poly(ester-amides), poly(ester-imides), poly(ester-imide-amides), etc. In the preferred embodiment such resins contain tris (hydroxyethyl) isocyanurate. The preferred IDA, which is derived from trimellitic anhydride (TMA) and glycine, has the following idealized formula ##STR2## IS THE PREDOMINANT DICARBOXYLIC ACID EMPLOYED IN SUCH RESINS. This invention also relates to aromatic IDA where R is aryl as illustrated by IDA derived from aminobenzoic acid and resins prepared therefrom.
