Abstract: 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/PSblend film is actually composed by a crystalline PPOphase and a non crystalline compatible PPO-PSphase. 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.
