Polyurethanes from Isosorbide-Based Diisocyanates

Benign building blocks: Stereochemically pure diisocyanates were 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‐...

Zusammenfassung:Benign building blocks: Stereochemically pure diisocyanates were 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.
