In powdery poly(2,6-dimethyl-1,4-phenylene oxide)-poly(6-hexanelactam) diblock copolymers, the occurrence of an amorphous interphase consisting of both the blocks was indirectly proved by calorimetric and sorption methods. The copolymer shows a compatibilizing effect in solution-cast films made from the blends of both homocopolymers.
