prepared on a multigram scale from succinic anhydride and isosorbide or isomannide. Characterization of polyurethanes that were produced from these diisocyanates revealed low polydispersity, high thermal stability, and stereochemistry‐dependent morphology. If biobased succinic anhydride is used, then no stoichiometric petroleum‐derived reagents are required in the synthesis of these materials.
良性构建基块:从琥珀酸酐和异山梨醇或异甘露糖醇以数克规模制备立体化学纯的二异氰酸酯。由这些二异氰酸酯生产的聚氨酯的表征显示出低的多分散性,高的热稳定性和立体化学相关的形态。如果使用生物基琥珀酸酐,则在合成这些材料时不需要化学计量的石油衍生试剂。
