This study aims at synthesizing alkyd resins from rubber seed oil (RSO), soybean oil (SBO), and their blends via the monoglyceride route. Oil extracted from rubber seeds was blended with soybean oil at various blending ratios (80:20, 70:30, 50:50, 30:70, and 10:90). Thereafter, the blends were employed in the synthesis of polyesters (alkyd resins) via alcoholysis technique. The alkyd samples synthesized from the RSO, SBO, and their respective blends were characterized for comparative purpose. The RSO-/SBO-based alkyds and aforementioned blends have iodine values of 157.90/142.00, 152.44, 149.90, 143.16, 142.26, and 142.41 gI₂/100 g and saponification values of 216.21/228.61, 203.67, 171.04, 161.97, 142.89, and 135.62 mgKOH/g, respectively. The drying property (set-to-touch time and the tack free) of the 100% RSO-based alkyd resin did not experience any significant improvement as the blending proportion of SBO in RSO increases. The tack-free and dry-through times for the blends were estimated to be around 129–133 and 236–243 min, respectively. Huggins and Kraemer viscosity relationship was used to extrapolate the intrinsic viscosities of the RSO- and SBO-based alkyds and their corresponding blends. The blends showed resistance to brine, water, and acid. However, only some exhibited fair resistance to alkali. The results from the investigation revealed that the alkyds prepared using a blend of RSO/SBO oil possess coating properties whose values are comparable to those of commercial polyesters. However, the studied SBO cannot be considered as good blending oil with RSO for the preparation of alkyd for the improvement of drying properties.

这项研究旨在通过单甘油酯途径从橡胶籽油（RSO），大豆油（SBO）及其混合物中合成醇酸树脂。从橡胶籽中提取的油与大豆油以各种混合比（80：20、70：30、50：50、30：70和10:90）混合。之后，将共混物用于通过醇解技术合成聚酯（烷基树脂）。从RSO，SBO及其各自的混合物中合成的醇酸树脂样品进行了表征，以作比较之用。基于RSO / SBO的醇酸树脂和上述混合物的碘值分别为157.90 / 142.00、152.44、149.90、143.16、142.26和142.41 gI ₂/ 100 g和皂化值为216.21 / 228.61、203.67、171.04、161.97、142.89和135.62 mgKOH / g。100％RSO基醇酸树脂的干燥性能（接触时间和不粘手性）没有任何显着改善，因为SBO在RSO中的混合比例增加。共混物的不粘手和干燥时间分别约为129-133分钟和236-243分钟。使用Huggins和Kraemer粘度关系来推断基于RSO和SBO的醇酸树脂及其相应共混物的固有粘度。混合物显示出对盐水，水和酸的抵抗力。然而，只有一些表现出对碱的中等抵抗力。研究结果表明，使用RSO / SBO油的混合物制备的醇酸树脂具有可与商业聚酯相比的涂层性能。然而，所研究的SBO不能被认为是与RSO的良好的调合油，用于制备醇酸树脂以改善干燥性能。
