Abstract
Di-substituted maleic anhydride compounds are disclosed of the structural formula ##STR1## wherein R and R.sup.1 are selected from the group consisting of aliphatic and phenyl moieties, and R.sup.2 is a divalent aromatic moiety. Polyamide-imide polymers, polyimide polymers and vinyl copolymers derived therefrom are also disclosed.
