Normally amorphous miscible blends of a copolyester and polycarbonate in the form of injection molded bars and extruded film were thermally annealed above the blend T g to cause the copolyester component to crystallize, and the resulting mechanical properties were evaluated. The properties were found to depend in a complex way on blend composition, annealing conditions employed, the initial state of molecular orientation, and the process history.
