Thermal behaviour of poly(acryloyloxybenzoic acid)/nylon 6 blends

The thermal behaviour of poly(acryloyloxybenzoic acid) (PABA)/nylon 6 (PA6) blends were investigated by differential scanning calorimetry. Melting point ( T m) of PA6 depressed with increasing PABA content. When PABA content was larger than about 60 wt%, second endotherm was observed above the T m (...

Description
Summary:The thermal behaviour of poly(acryloyloxybenzoic acid) (PABA)/nylon 6 (PA6) blends were investigated by differential scanning calorimetry. Melting point ( T m) of PA6 depressed with increasing PABA content. When PABA content was larger than about 60 wt%, second endotherm was observed above the T m (first endotherm). Wide angle X-ray diffraction analysis suggested that crystallinity of PA6 was decreased with increasing PABA content. The second endotherm could be assigned to the melting of PA6–PABA complex.
