Poly(vinyl alcohol) (PVA) was crosslinked via catalyst-free solid-state esterification at 120 °C with 2,5-furandicarboxylic acid (FDCA) at concentrations ranging from 1 to 10%. The thermal stability of PVA was improved significantly, especially at low FDCA concentrations of 1 and 5%, where degradation maximums occurred at 354 and 371 °C, respectively, compared to 267 °C for unmodified PVA. A twofold increase in tensile strength for the biodegradable PVA was achieved by crosslinking with 5% FDCA.
