High barrier biosourced polyester from dimethyl [2,2′-bifuran]-5,5′-dicarboxylate

Furfural-Based Modification of PET for UV-Blocking Copolymers with Decreased Oxygen Permeability

“…As described in the literature, both PEF and PEBF have a higher T g than PET despite their lower or similar melting points. [32][33][34]43 Thus, the increased glass transition range and lower melting temperature were expected as a result of incorporating BFDCA into PET. Obvious endothermic and exothermic peaks derived from melting and crystallization, respectively, were observed in the first heating scan (Figure 2a) for all semicrystalline copolymers except PET 85 BF 15 .…”

“…A potential drawback of the 2,2′bifuran structure was also studied and discussed, i.e., the degradation of PEBF by oxygen at high temperatures. 33 In terms of BFDCA-containing copolyesters, little work has been done to date. A series of random copolyesters including poly(butylene furanoate) (PBF) and poly(butylene bifuranoate) (PBBF) was recently described by our group.…”

Sustainable aromatic polyesters with 1,5-disubstituted indole units

“…[22][23][24][25][26][27][28][29][30][31] Among these building blocks, furan-based ones have attracted the most attention. [32][33][34][35][36][37][38][39] Particularly, 2,5-furan-dicarboxylic acid (FDCA) has been conveniently produced from sugar resources and used to synthesize various polyesters. [40][41][42][43][44][45][46] For example, polyethylene furanoate (PEF) is a fully biobased polyester, which can be prepared using FDCA and bio-based ethylene glycol.…”

Isosorbide and Tricyclodecanedimethanol for the Synthesis of Amorphous and High Tg Partially Biobased Copolyesters

“…Several diacids/diesters such as purified terephthalic acid (PTA) and 2,5-dimethyl furanedicarboxylate − (DMFD) were also investigated. Recently, new insights have been gained on bicyclic structures such as 3,4′-bibenzoate (3,4′BB) and 4,4′-bibenzoate , (4,4′BB), indole (IND), divanillic acid, and dimethyl [2,2′-bifuran]-5,5′-dicarboxylate. , …”

“…Recently, new insights have been gained on bicyclic structures such as 3,4′-bibenzoate (3,4′BB) and 4,4′-bibenzoate 17,18 (4,4′BB), indole 19 (IND), divanillic acid, 20 and dimethyl [2,2′-bifuran]-5,5′-dicarboxylate. 21,22 It is relevant to underline that some of these monomers are biobased and/or industrially available. Some of them are expected to be produced from renewable feedstocks at a larger scale in the future, such as PTA and CHDM.…”
