The solvent-resistance and thermal stability of polyamideimides of the general formulae: ##STR1## is improved by capping the amideimides with a crosslinking functionality (Y) containing a residue selected from the group of: ##STR2## wherein R 1 =lower alkyl, lower alkoxy, aryl, aryloxy, substituted alkyl, substituted aryl (either including hydroxyl or halo-substituents), halogen, or mixtures thereof; n j=0, 1, or 2; n G=--CH 2 --, --O--, --S--, --SO 2 --, --SO--, --CO--, --CHR--, or --C(R) 2 --; n R=hydrogen, lower alkyl, or phenyl; n T=methallyl or allyl; n Me=methyl; n R 2 =a trivalent organic radical; and n R 3 =a divalent organic radical. n The amideimide oligomers may be linear or multidimensional, and can be processed into blends, prepregs, or composites. Methods of making these amideimides and intermediates useful in the syntheses are also described. One such intermediate has the general formula: n n Y.sub.i --CONH--R.sub.3 --NH.sub.2 n n and is the focus of the present application. |
