Solvent resistance in polyimide, polyamide, and other resins can be improved by capping these resins with mono- or difunctional crosslinking end caps. Imidophenylamines of the general formula: Image wherein Y = Image , Image , Image , Image , Image , or Image R1 = lower alkyl, lower alkoxy, aryl, aryloxy, substituted aryl, substituted alkyl, 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.
