Solvent resistance in polyimide, polyamide, and other resins can be improved by capping these resing with mono- or difunctional crosslinking end caps. Imidophenylamines of the general formula: [Figure] [Figure] [Figure] [Figure] R1=lower alkyl, lower alkoxy, aryl, aryloxy, substituted alkyl, substituted aryl, halogen, or mixtures thereof; Me=methyl; T=allyl or methallyl; i=1 or 2; j=0, 1, or 2; and G=-CH2--O-, -S-, or -SO2-. comprise a new family of end cap monomers that are reactants in the synthesis of crosslinking, solvent resistant oligomers. The imidophenylamines are prepared by reacting the corresponding acid halide with ammonia to form an amic acid and rearranging the amic acid to the amine.
