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, aver- age 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 exhi- bited superior moisture uptake, which prompted further characterization us- ing 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, cha- racterization, and comparative properties of Sesamum indicum seed oil-derived alkyds with varying oil lengths. The findings contribute to a deeper under- standing of their unique attributes and potential applications.
