Study on the Compatibility of PTT/PA6 Blends

Blending technics and compatibilizing methods for PTT/PA6 blending systems were studied via DSC, SEM analysis. The results indicated that the compatibility of the systems hadn't been evidently improved when blending time was prolonged, but had been improved a lot when blending temperature was increased because of the existence of ester-amide exchange reaction. Study on another way that using compatibilizer to improve the compatibility showed that when 4 % of compatibilizer PE-g-MAH was added in the system, the compatibility was improved evidently.
