The synthesis and characterization of Sesamum indicum seed oil have been thoroughly examined. The seed oil was extracted and utilized in formulating alkyds with varying oil lengths of 40%, 50%, and 60%. The in-situ process for the synthesis was analyzed, revealing significant properties associated with the different oil lengths, including changes in degree of polymerization, average molecular weight, and, notably, the extent of reaction favoring the 40% oil length alkyd resin. Furthermore, the chemical resistances of the various oil lengths were assessed to determine their susceptibility to acidic, basic, brine, and distilled water media. Encouragingly, all the alkyd resins demonstrated good chemical resistance. Additionally, the 40% oil length alkyd resin exhibited superior moisture uptake, which prompted further characterization using Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, and differential scanning calorimetry. These techniques were employed to explore the exceptional properties of the 40% oil length alkyd resin. Overall, this research sheds light on the synthesis, characterization, and comparative properties of Sesamum indicum seed oil-derived alkyds with varying oil lengths. The findings contribute to a deeper understanding of their unique attributes and potential applications.
