This study valorises the benign epoxidation of (R)-(+)-limonene to generate novel bio-resourced limonene dioxide monomers. Without additional steps of separation or functionalization, the racemic limonene dioxide was cured with glutaric and dimethylglutaric anhydrides leading to thermosets with a high T_g (∼98 °C) and good mechanical properties (σ = 27 MPa; ε = 3.5%; E = 1150 MPa; E′ = 1650 MPa, Shore D = 78).

二氧化柠檬烯作为 100% 生物基热固性塑料的基石

该研究评估了 ( R )-(+)-柠檬烯的良性环氧化反应，以产生新型的生物资源柠檬烯二氧化单体。没有额外的分离或功能化步骤，外消旋二氧化柠檬烯用戊二酸和二甲基戊二酸酐固化，导致热固性材料具有高T _g (~98 °C) 和良好的机械性能 ( σ = 27 MPa; ε = 3.5%; E = 1150 兆帕；E ' = 1650 兆帕，邵氏D = 78）。
