These blends exhibit a linear relationship between IV (determined by both titration and <sup>1</sup>H-NMR methods) and mass fraction. By combining vegetable oils with varying IVs, blends can be used to achieve the desired unsaturation level providing a continuous supply of raw materials for the polymer industry. Thus, to validate this approach, a polymer was synthesized using a blend of Brazil nut and linseed vegetable oils, resulting in an IV equal to 123.5 g of I<sub>2</sub> per 100 g of sample. This polymer exhibited comparable properties, including thermal stability (265 °C) and glass transition temperature (-14.7 °C), to a polymer made from pure grape seed oil with an IV of 123.0 g of I<sub>2</sub> per 100 g. These findings confirm that the desired IV can be achieved through simple blending based on a linear relationship between IV and mass fraction.
