Synthesis and kinetic modeling of biomass-derived renewable polyesters

ABSTRACT The biomass‐derived polyesters poly(1,3‐propylene 2,5‐furandicarboxylate) (PPF), poly(1,3‐propylene succinate) (PPS) and poly(1,3‐propylene 2,5‐furandicarboxylate‐co‐1,3‐propylene succinate) (PPFPS) have been synthesized via a two‐step process involving polycondensation and azeotropic distillation. The kinetic parameters were obtained by fitting the experimental data from a batch polymerization reactor to three different kinetic models for polyesterification reactions. The activation energies of the all monomer systems were obtained by Arrhenius plots. Given the increasing availability of biomass‐derived monomers their use in renewable polyesters as substitutes for fossil fuel derived chemicals becomes a distinct possibility. The kinetic modeling of the uncatalyzed polyesterification reactions will enable further integrative process simulation of the studied bioderived polymers and provide a reference for future practical study or industrial applications of catalyzed polyesterification reactions and other bioderived monomer systems. © 2016 The Authors.

Chem. 2016, 54, 2876–2887 Biobased polyesters are synthesized via polyesterification of 2,5‐furandicarboxylic acid and succinic acid with 1,3‐propanediol. Data is fitted to different rate equation models and kinetic coefficients and activation energies acquired. This work is to be used for further complex kinetic modeling and polymerization process simulation. The increasing availability of biomass‐derived monomers makes the production of renewable polyesters as substitutes for fossil fuel derived chemicals a distinct possibility.
