A facile method to synthesize high‐molecular‐weight biobased polyesters from 2,5‐furandicarboxylic acid and long‐chain diols

26.06.2015 | Vasilios Tsanaktsis, George Z. Papageorgiou, Dimitrios N. Bikiaris, Journal of Polymer Science Part A: Polymer Chemistry, 2015

ABSTRACT In this study, biobased furan dicarboxylate polyesters have been prepared using 2,5‐furandicarboxylic acid (FDCA) and diols with high number of methylene groups (long‐chain diols), namely, 8, 9, 10, and 12. Because of the high boiling points of these diols, a modified procedure of the ...
