摘要
如今,从不可再生资源中提取聚合物的现象十分普遍。因此,对植物油等环境可持续替代品的需求不断增加。然而,植物油在聚合物生产中的大规模使用受到季节性和地区供应的阻碍。为了应对这些挑战,本研究证明了制造具有精确碘值(IV)的植物油混合物的可行性,碘值是聚合反应的关键参数。这些混合物的碘值(通过滴定和 1H-NMR 方法测定)与质量分数之间呈线性关系。通过组合不同 IV 值的植物油,混合物可以达到所需的不饱和水平,为聚合物行业提供持续的原料供应。因此,为了验证这种方法,我们使用巴西坚果植物油和亚麻籽植物油的混合物合成了一种聚合物,其 IV 值等于每 100 克样品中含 123.5 克 I2。这种聚合物的热稳定性(265 °C)和玻璃化转变温度(-14.7 °C)与纯葡萄籽油制成的聚合物(IV 值为每 100 克样品含 123.0 克 I2)具有可比性。因此,这种方法能够生产出与使用单一植物油所获得的特性相似的聚合物,从而扩大了可持续聚合物制造的潜力。
Linear dependence of iodine value on the mass fraction of vegetable oils: a new way to overcome seasonal challenges for renewable polymer manufacturing
Polymers derived from non-renewable sources are prevalent today. The demand for environmentally sustainable alternatives, such as vegetable oils, is consequently increasing. However, the large-scale utilization of vegetable oil in the polymers production is hindered by seasonality and regional availability. To address these challenges, this study demonstrates the feasibility of creating vegetable oil blends with precise iodine values (IVs), a critical parameter for polymerization. These blends exhibit a linear relationship between IV (determined by both titration and 1H-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 I2 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 I2 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. Therefore, this approach enables the production of polymers with properties similar to those obtained using a single vegetable oil, thereby expanding the potential for sustainable polymer manufacturing.
