Biorenewable resources can be used as green monomers to design tailored structures for formulations that can play an important role as functional materials. The choice of optimal structures depends on the targeted properties and applications. This work focuses on the elaboration of biobased materials with toughened mechanical properties based on epoxidized linseed oil. This result was obtained by an overall approach of cross-linking process, that is, starting with the optimal choice of hardeners and finally favoring the side reactions of polymerization. Therefore, the anionic alternating copolymerization of epoxide with mono- and dianhydrides was investigated to tailor the parameters that led to maximal conversions and properties. The obtained highly cross-linked networks perform well, as demonstrated by good impact strengths, high glass transition temperatures, and excellent thermal stability, which opens up the possibility of using these emergent materials for industrial applications.
生物可再生资源可用作绿色单体，为配方设计定制结构，可作为功能材料发挥重要作用。最优结构的选择取决于目标性能和应用。这项工作专注于基于环氧化亚麻籽油的增韧机械性能的生物基材料的阐述。这一结果是通过交联过程的整体方法获得的，即从最佳选择硬化剂开始，最终有利于聚合的副反应。因此，研究了环氧与单酐和二酐的阴离子交替共聚，以调整导致最大转化率和性能的参数。所得到的高度交联网络表现良好，如良好的冲击强度、高玻璃化转变温度和优异的热稳定性所证明的那样，这为这些新兴材料在工业应用中的使用开辟了可能性。
