Poly bisphenol a carbonate

2,5-furan dicarboxylic acid (purum 97%) tetrabutyltitanate (TBT) catalyst of analytical grade and 1,4-Butanediol of analytical grade used in polyester synthesis, were purchased from Sigma-Aldrich Chemical Co. (Chemie GmbH, Steinheim, Germany). All other materials and solvents used were of analytical grade.
High molecular weight poly(ethylene 2,5-furandicarboxylate) (PEF), poly(propylene 2,5-furandicarboxylate) (PPF), poly(butylene 2,5-furandicarboxylate) (PBF) and poly(1,4-cyclohexanedimethlene 2,5-furandicarboxylate) were synthesized by applying melt polycondensation following the general procedure shown in Scheme 1 and described in detail in our previous studies [16 (link),19 (link),32 (link),60 (link)]. Solid-state polycondensation (SSP) was subsequently applied to produce polymers of high molecular weight at 220 °C and 170 °C for PEF and PPF, respectively, for 8 h. PET, PPT, PBT and PBN were also prepared, as described in our previous studies, by melt polycondensation procedure [39 (link),40 (link)]. PLA with average molecular weight Mn = 20,000 Da and polydispersity index about 1.3 and poly(bisphenol A carbonate) with average Mw about 45,000 were purchased from Sigma Aldrich Chemical Co.

The main compound, 2,5-furan dicarboxylic acid (97% purity), was purchased from Sigma-Aldrich Chemical Co (Chemie GmbH, Steinheim, Germany).

High-molecular-weight poly(butylene 2,5-furandicarboxylate) (PBF) was synthesized by applying melt polycondensation following the general procedure described in our previous study [21 (link)]. PET, PPT, and PBN were also prepared, as described in our previous studies, via the melt polycondensation procedure [39 (link),40 (link)]. PLA, with an average molecular weight of Mw = 20,000 Da and a polydispersity index of about 1.3, and poly(bisphenol A carbonate), with an average Mw of about 45,000 Da, were purchased from Sigma-Aldrich Chemical Co.
