Thiol-Ene Click Cross-linking of Starch Oleate Films for Enhanced Properties.

Biobased films were synthesized from starch oleate (DS = 2.2) cross-linked with polyethylene glycol with = 2000 and 1000 g · mol, and ethylene glycol, all of which were esterified with either lipoic acid (LA) or 3-mercaptopropionic acid (MPA). Cross-linking was achieved through a UV-initiated thiol-ene click, and confirmed by Fourier transform infrared spectroscopy and rheometry.
