以转基因大豆油为原料，以过氧化二氨基（DCP）或硫为反应试剂，设计合成了新型生物基超支化聚合物。采用傅里叶变换红外光谱和核磁共振方法对样品的结构和反应机理进行了验证和研究。凝胶渗透色谱（GPC）结果表明，通过控制反应试剂的用量可以很容易地调节全大豆油基聚合物的分子量，而不是改变反应时间。采用溶液-沉淀法可以完全去除DCP引发聚合物中的低聚物和分解产物，最终得到了几种纯化的大豆油基高分子量超支化聚合物。这项工作对超支化聚合物的可持续性做出了很大的贡献。
New biobased hyperbranched polymers were designed and synthesized from transgenic soybean oil by using dicumyl peroxide (DCP) or sulfur as reaction reagents. The structures of the samples and the reaction mechanisms were confirmed and investigated by Fourier transform infrared spectroscopy and nuclear magnetic resonance methods. The gel permeation chromatography (GPC) results showed that the molecular weight of the fully soybean-oil-based polymers could be easily adjusted by controlling the amounts of the reaction reagents rather than vary the reaction time. The oligomers and decomposition products of DCP in the DCP-initiated polymers could be completely removed by using a solution–precipitation method, and finally, several purified fully soybean-oil-based hyperbranched polymers with high molecular weights were obtained. This work makes a great contribution to the sustainability of hyperbranched polymers.
