Moreover, the gap between the PA66 and PPO glass-transition temperatures decreases with the SAG content increasing, which indicates improved compatibility. The particle morphology of the PA66/PPO/SAG blends had narrower size distributions and became smaller after adding SAG. In addition, the compatibilization improved the mechanical properties of blends significantly when SAG reached 5 by weight per hundred resins (phr). This is attributed to enhanced interfacial adhesion and a finer dispersion morphology.
