Abstract Polymer blends of two components, in general, are not miscible. However, according to Karasz‐MacKnight theory, intramolecular repulsion may outweigh intermolecular repulsion and cause two polymers to have a net interaction. Using a simple short chain molecular model incorporating both interand intramolecular interactions, estimates of net interaction energies for a series of polymeric imides, benzimidazoles and related high‐performance polymers can be calculated and used to predict miscibility in excellent agreement with experimental results, thus providing a useful confirmation of theory and a focus for the direction of further experimental work.
