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.

“…M c indicates chain entanglement and is about twice as large as the molecular weight between entanglements ( M e ) ( M c ≈ 2 M e ) . It is about 5 kDa in similar polyesters (compare to M n ) . Essentially, M c is the molecular weight at which the viscosity of the polymer melt starts increasing more rapidly with increasing molecular weight, due to the presence of entanglements .…”

The positional effect of sulfonate groups on poly(butylene succinate) (PBS) microstructure was investigated. In this regard, unsaturated poly(butylene fumarate) (PBF) and poly(butylene succinate‐ran‐fumarate) copolymers, synthesized via esterification/polycondensation reactions, were modified through post‐polymerization modification. The progress of the PBF sulfonation reaction was analyzed via 1H NMR, dynamic light scattering and field emission SEM. The microstructure and thermal behavior of the functional polyesters were studied through DSC, TGA, elemental analysis and 1H NMR. Based on the results, the sulfonation reaction of unsaturated polymer chains, which are not experiencing a phase separation, is instantaneous, but sulfonation of the chains that have formed colloidal particles is a time‐consuming process. Surprisingly, the outcomes of 1H NMR analysis revealed a kind of heterogeneity along the fully sulfonated PBS backbone, similar to what is usually observed for copolymers. This is due to the ability of sulfonate groups to locate in different sites and create various block types. Due to the attraction between sulfonate groups, they tend to attach to the chain such that they provide the greatest number of second type blocks (containing two sulfonate groups). The randomness of sulfonated polymers after the sulfonation reaction was increased compared to that of the corresponding unsaturated copolymers. Increasing the content of sulfonate groups also led to a significant decrease in the thermal resistance (ca 120 °C) and crystallinity, along with a dramatic increase in ash content and Tg (up to 156 °C). © 2018 Society of Chemical Industry

“…The obtained molar masses can be considered low for applications that require good mechanical properties, but seem adequate for manufacture of microparticles intended for cosmetic applications and are higher than molar masses reported in other studies and obtained at more severe reaction conditions . For the sake of comparison, Chen et al studied the synthesis of several biomass polymers; for the specific case of PBS, the reaction was performed with the catalyst TTP (titanium tetraisopropoxide) and led to PBS resins with Mn of 3000 Da after 20 h of reaction at 220 °C.…”

Studies regarding sustainability are growing, making the production of bio‐based polymer products, such as poly(butylene succinate) (PBS), a promising new alternative for sustainable development and manufacture of eco‐efficient products. In this context, the main objective of the present study is the production of PBS microbeads through a water‐free suspension polycondensation processes. The obtained results indicate that it is possible to produce PBS microbeads through polycondensation in heterogeneous media, overcoming the natural mass transfer limitations related to the removal of the condensation byproduct (water) from suspended particles, and simultaneously allowing for production of condensation polymer particles in the micrometric region. Besides, the proposed process route promoted shorter reaction times than conventional polycondensations and production of PBS microparticles with controlled sizes and molar mass distributions. The produced particles presented average sizes ranging from 80 to 180 μm, with melting points ranging from 105 to 112 °C and average molar masses around 1.3 × 104 Da.
