摘要：
Thermal evolution behavior of solution-cast film of Poly (2,6-dimethyl 1,4-phenylene oxide) (PPO)/polystyrene (PS) blend was investigated by conventional and modulated differential scanning calorimetry. It was found that the original PPO/PS blend film is actually composed by a crystalline PPO phase and a non-crystalline compatible PPO-PS phase. The phase-segregated structure state(A) will evolve to non-crystalline homogenous structure(B) by subsequent thermal treatment. The effect of annealing temperature on the evolution process was discussed.
