Synthesis and molecular characterization of chitosan based polyurethane elastomers using aromatic diisocyanate.

Highlights: [•] New chitosan based polyurethane elastomers (PUEs) were synthesized. [•] Molecular engineering was carried out during the synthesis using FT-IR. [•] The FT-IR confirms the existence of the proposed chitosan based PUEs structure. [•] Internal morphology of the prepared PUEs was studied using SEM analysis. [ABSTRACT FROM AUTHOR]
