The thermomechanical properties of the synthesized copolymers were analyzed using DMTA. DMTA enables the characterization of a polymer's viscoelastic behavior, including its storage modulus, loss modulus, and damping properties, which are essential for predicting material response to mechanical stress, optimizing printing parameters, and dimensional accuracy and structural integrity of printed parts . By understanding and tailoring the thermomechanical properties, 3D printing processes can be fine-tuned to achieve superior quality and functional performance of printed parts for a wide range of applications. Figure represents the DMTA results of the copolymers investigated in a temperature range from -80°C to 90°C, including storage modulus (E') and tan delta (tan ). The storage modulus results indicate the relaxation in the copolymers, which is represented by transition temperature (Tg), which started declining down from around -40°C. For the samples with lower hard segments content (60 wt%), the E' values were slightly lower than for those with higher hard segments content (70 wt%), which indicates the lower degree of crystallinity for the first one. Additionally, based on the E' values, copolymers with lower hard segments content (60 wt%) started to flow at lower temperature compared to those with higher hard segment content (70 wt%) which indicates the lower molecular weight (see Table ). Tan  curves represent the damping properties of the copolymers at subzero region around Tg. Overall, the appearance of the tan δ curves as sharp peaks indicates high homogeneity of the amorphous phase. Decreasing the amount of hard segments ratio from 70 wt% to 60 wt%, however, triggers higher values of tan δ which indicate more intensive damping properties.
