ABSTRACT:
This invention relates to imino dicarboxylic acids (IDA) of the general formulae ##STR1## and ##STR2## where 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 ##STR3## and IS THE PREDOMINANT DICARBOXYLIC ACID EMPLOYED IN SUCH RESINS.
