Evaluation of Fatty Acid Waste in the Synthesis of Oligo (Ether-Ester)s. International Journal of Polymer Science, 2019.1687-94221687-9430https://dx.doi.org/10.1155/2019/1519593https://hdl.handle.net/20.500.12395/37806In this study, the waste of sunflower oil refinement was converted to a fatty acid glycidyl ester (FAGE). An unsaturated oligo(ether-ester) (OEE) was synthesized by ring-opening polymerization using propylene oxide (PO) and FAGE. Oligo(ether-ester) production was achieved with a high yield of 80% at 5 h and 0 degrees C when the mole ratio of PO : FAGE was 1 : 1. Synthesized OEE was characterized by FTIR and several chemical analysis methods. According to the TGA results, T-5, T-10, and T-50 values of OEE-styrene copolymers increased up to a 7 : 3 mole ratio then decreased. The weight losses of these copolymers changed in the range of 3-5%. The data of longitudinal and transversal wave velocities showed that copolymers with styrene had better elastic properties and impact resistances compared to those with pure polystyrene.en10.1155/2019/1519593info:eu-repo/semantics/openAccessfatty acidoligoethersestersArticleQ2WOS:000464781100001Q3
