Evaluation of Fatty Acid Waste in the Synthesis of Oligo(Ether-Ester)‎s

Abstract EN

In 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°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, T5, T10, and T50 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.
