Natural vegetable oils have the potential to provide functionally equivalent, renewable and environmentally friendly replacements for fossil-based raw materials, provided well industrial demands. In this study, we have developed eco-friendly thermoplastic poly (ether ester) elastomers (TPEE) using N,N’-bis(2-hydroxy ethyl) soybean oil fatty amide (SOFA) as a chain extender. The SOFA was derived from soybean oil (SBO) by reacting with diethanolamine. Further, the SOFA characterized by using 1H NMR and 13C NMR. A series of TPEEs were synthesized by using SOFA and 1,4-butanediol based chain extender, poly (tetramethylene ether glycol) as soft segment, and dimethyl-2,6-naphthalenedicarboxylate as hard segment. The relative chain extender composition of 1,4-butanediol/SOFA was changed by varying molar ratio from 99/1 to 80/20. The mechanical properties, thermal behavior and spectroscopic analyses of resultant TPEEs were systematically characterized. |
