All samples of the chemical structure were determined via Fourier transform infrared spectroscopy (FT-IR). The lowest melting temperature (Tm) located in 123.4 °C with the BAEA/AA content of 10 mole% that was obtained via differential scanning calorimetry (DSC). In addition, the best mechanical properties were observed from the BAEA/AA content of 5 mole%, which the tensile strength and elongation at break were shown at 59.5 MPa and 542.3 %, respectively.
