Abstract

Compositions made from a polyarylate or polyester carbonate containing greater than about 50 mole % resorcinol based ester linkages give miscible blends with polyimide resins. The blends of polyimides and resorcinol based polyesters or resorcinol based polyester carbonates also give miscible blends when combined with other aryl alky polyester resins.
