Morphology evaluation of biodegradable copolyesters based on dimerized fatty acid studied by DSC, SAXS and WAXS

Popis výsledku v původním jazyce

Aliphatic copolyesters of succinic acid (SA) and dimerized fatty acid (saturated dilinoleic acid (DLA)) were synthesized via direct copolycondensation in the presence of 1,4-butane-diol. 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 increasingcontent 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.
