Synthesis and Kinetic Modeling of Biomass-Derived Renewable Polyesters

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 twostep 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 biomassderived 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.
