摘要

The effect of processing conditions on mechanical properties of poly(styrene-b-ethylene-co-butylene-b-styrene) (SEBS) and poly(2,6-dimethy-1,4-phenylene oxide) (PPO) blends were investigated. Differential scanning calorimetry and small angle X-ray scattering were used to study the miscibility and d-spacing of the blends. The processing temperature plays an important role in mechanical properties. PPO works as filler and weakens mechanical properties when the processing temperature is below 230 degrees C. As the processing temperature exceeds 230 degrees C, PPO incorporates into the PS blocks of SEBS and the performance enhances with increasing temperature due to a better miscibility. The strong shear stress is beneficial to the dispersion of PPO into SEBS matrix and more PPO incorporates into PS blocks during melt processing, resulting in the better mechanical properties and a larger d-spacing.
