介绍了一种以植物油为原料合成高分子材料的新工艺。首先，在惰性气氛下，将亚麻籽油在300°C下进行热聚合。接下来，将得到的油分在无溶剂的两步一次工艺中进行功能化，以便接枝到一些可光聚合的基团上。第一步是在惰性气氛下与马来酸酐在220℃下进行体反应。接枝的酸酐基团在第二步中作为锚点在室温下接枝甲基丙烯酸2-羟乙酯。最后，对改性后的亚麻籽油进行紫外固化制备材料，并对其进行表征。所获得的材料具有柔韧性、疏水性和不可生物降解性，在柔性涂料中具有潜在的应用前景。
A new synthesis process of polymer materials based on vegetable oil has been developed. First, linseed oil was thermally polymerized in bulk at 300 °C under an inert atmosphere. Next, the obtained stand oil was functionalized in a two-step one-shot process without solvent in order to graft on some photopolymerizable groups. The first step consisted of a bulk reaction with maleic anhydride at 220 °C under an inert atmosphere. The grafted anhydride groups were then used in the second step as an anchor for grafting 2-hydroxyethylmethacrylate at room temperature. Finally, the materials were prepared by UV-curing of the modified linseed oil and then characterized. The obtained materials are flexible, hydrophobic and not biodegradable, and may have potential applications in flexible coatings.
