The thermal and mechanical properties of these copolymers were investigated as a function of the hard/soft segments' ratio. The results of small-angle X-ray scattering (SAXS) investigations revealed that the characteristic d spacing of the copolyester supermolecular structure increases from 7 nm to 14 nm with increasing content of soft segments, DLA. It was found that the crystalline phase content determined by WAXS increases from 22 to 66% and was found to increase with increasing content in polybutylene succinate (PBS) sequences and increasing polybutylene succinate (PBS) sequence length.
