Therefore, based on previous experiences with copolymers containing dilinoleic diol, we selected the composition of 70-30 wt% hard to soft segments for further exploration of their structure and properties in the context of future materials for medical sector. This specific ratio demonstrated a favorable combination of properties, including high flexibility with good mechanical performance, and dimensional stability. However, the potential for the sterile barrier system has not been explored yet, especially in the context of using aliphatic diols of variable chain length to change the distance between the spiral motifs of the carboxyls of FDCA and thus manipulate the final properties, and it will be discussed for the first time in this work. Therefore, the outcomes of this research hold significant promise for advancing the development of environmentally sustainable materials for medical sector.
