Synthesis of biosourced polyether-amides from 1,4-3,6-dianhydrohexitols: Characterization by NMR and MALDI-ToF mass spectrometry

Résumé

New series of polyether-amides were prepared by polycondensation in solution of three diamines based on 1,4-3,6-dianhydrohexitols with two types of diacyl chlorides (sebacoyl and isophtaloyl). Unprecedented diamines based on isomannide and isoidide were elaborated. The corresponding polyether-amides (PeA) were obtained with high yields. They were characterized by different analytical techniques (NMR, MALDI-ToF MS, DSC). The combination of MALDI-ToF MS with NMR spectroscopy allowed us to confirm structure types. DSC measurements revealed an amorphous character for the isophtaloyl family with a high Tg value. The sebacoyl series proved to be semi-crystalline with a high Tm value. Isosorbide-based PeAs demonstrated interesting properties (Tg above 210 °C and Tm above 240 °C) and high viscosity (0.32).
