ABSTRACT:
This invention relates to heat-resistant polyimide blends and laminates thereof, which have excellent heat and moisture resistance, and excellent mechanical properties, including outstanding toughness. The blends contain a thermoplastic polyimide component and a thermosetting imide oligomer. The weight ratio of the thermoplastic component to thermosetting component is selected in the range of 99/1 to 5/95. The thermoplastic polyimide component has a number average molecular weight of 10,000 or more.
