摘要

The polyamide 66 (PA66)/poly(hydroxyl ether of bisphenol A) (PHE) blend was successfully prepared by twin-screw extrusion without the addition of any compatibilizer. The PA66/PHE blends had a microphase-separated structure that varied from a sea-island structure to a cocontinuous structure, and the mechanical properties were higher than the anticipated values on the basis of the rule of mixtures, which showed a synergistic effect. Fourier transform infrared spectroscopy and dynamic mechanical analysis illustrated that there was hydrogen-bonding interaction between the amide groups of the PA66 and the pendant hydroxyl groups of the PHE. This led to the some degree of compatibility and the improvement in the mechanical properties of the blends. The polarized optical microscopy observation showed that the PA66 spherulites of the blend became smaller and more imperfect compared to those of the pure PA66, and differential scanning calorimetry measurement also showed a decrease in the melting temperatures of PA66 of the blend.
