Biobased poly(butylene 2,5-furandicarboxylate) and poly(butylene adipate-co-butylene 2,5-furandicarboxylate)s: From synthesis using highly purified 2,5-furandicarboxylic acid to thermo-mechanical properties

Biobased polyesters and other polymers from 2,5-furandicarboxylic acid: a tribute to furan excellency

“…96,98 This same tendency was also observed for PBA-co-PBF copolyesters. 95,97 As expected, the thermal properties of the corresponding copolyesters were also affected by their crystalline structures (Table 2). In the case of PBF-co-PBS copolyesters, when BF content was lower than 10 mol%, T m values were c.a.…”

“…97,98 As it is well known, random copolymerisation usually results in a decreased melting point, degree of crystallinity and tensile strength. This phenomenon also occurred with PBF based copolymers; for instance, PBF-co-PBS copolyesters exhibited a crystalline structure when the content of butylene furandicarboxylate (BF) was lower than 20 mol% or higher than 70 mol% and nearly amorphous structure when the content of BF was between 30 and 60 mol%.…”

Progress of Polymers from Renewable Resources: Furans, Vegetable Oils, and Polysaccharides

“…The first such study described the synthesis and characterization of fully b i o b a s e d p o l y ( b u t y l e n e s u c c i n a t e -c o -b u t y l e n e furandicarboxylate)s, 31 followed by a similar approach for preparing poly(butylene adipate-co-butylene 2,5-furandicarboxylate)s, 32 in which the important issue of the purity of FDCA (often questioned and assumed to be the source of coloring in the ensuing polymers) was tackled with an original alternative purification process. These two copolymer families were shown to afford tunable properties as a function of the comonomer composition, ranging from crystalline polymers, possessing a good tensile modulus (360−1800 MPa) and strength (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35), to essentially amorphous polymers with a low T g and very high elongation at break (about 600%), useful as thermoplastics, elastomers, or impact modifiers. The copolyesterification system ethylene glycol/ FDCA/succinic acid was also studied, 33 and it showed that this material was a suitable alternative to poly(ethylene terephthalate-co-ethylene succinate) (PETS), a well-known PET copolymer.…”

Modification of poly(ethylene 2,5-furandicarboxylate) with 1,4-cyclohexanedimethylene: Influence of composition on mechanical and barrier properties

“…Taking the polyesters for example, by varying the type of diols, different polyesters derived from FDCA, such as poly(octylene 2,5-furandicarboxylate) (POF) [12], poly (ethylene 2,5-furandicarboxylate) (PEF) [15,21], poly(propylene 2,5-furandicarboxylate) (PPF) [22], poly(butylene 2,5-furandicarboxylate) (PBF) [23][24][25][26] and poly(hexamethylene 2,5-furandicarboxylate) (PHF) [27], have been synthesized. Among them, PEF might be the most promising one due to its higher glass transition temperature and better mechanical properties.…”
