Enzymatic synthesis of 2,5-furandicarboxylic acid-based semi-aromatic polyamides: enzymatic polymerization kinetics, effect of diamine chain length and thermal properties

Abstract

Sustainable FDCA-based semi-aromatic polyamides are produced via enzymatic polymerization. The enzymatic polymerization kinetics, effect of diamine chain length, and thermal properties of the resulting polyamides are investigated.

Advances in polymer precursors and bio‐based polymers synthesized from 5‐hydroxymethylfurfural

“…Additionally, the incorporation of other functional monomers to synthesize copolymers or the preparation of composites provide the opportunity to tune the thermal and mechanical properties of materials from bio‐based HMF and its derivatives . Finally, enzymatic catalysis is worthy of investigation due to the mild reaction conditions, environmental friendliness, and high tolerance toward functional groups …”
