This invention provides compositions containing A. A POLYIMIDE AND POLYAMIDE-IMIDE TERMINATED WITH OLEFINIC UNSATURATED END GROUPS, OR THE CORRESPONDING POLYAMIDE-ACIDS IN COMBINATION WITH A REACTIVE Schiff base compound, and B. A POLYIMIDE AND POLYAMIDE-IMIDE TERMINATED WITH A Schiff base end group

This invention provides compositions containing A. A POLYIMIDE AND POLYAMIDE-IMIDE TERMINATED WITH OLEFINIC UNSATURATED END GROUPS, OR THE CORRESPONDING POLYAMIDE-ACIDS IN COMBINATION WITH A REACTIVE Schiff base compound, and B. A POLYIMIDE AND POLYAMIDE-IMIDE TERMINATED WITH A Schiff base end group or the corresponding polyamide acids in combination with a reactive N,N′-bis-imide. These Schiff bases and N,N′-bis-imide compounds facilitate processing of the prepolymer resins by lowering the softening temperature, under processing conditions, and chain-extend and cross-link the base resins.
