New poly(pentylene furanoate) and poly(heptylene furanoate) sustainable polyesters from diols with odd methylene groups

In the current manuscript two new furan based polyesters, namely poly(pentylene furanoate) (PPeF) and poly(heptylene furanoate) (PHepF), have been synthesized for the first time using 2,5-furandicarboxylic acid (2,5-FDCA) and aliphatic diols with odd number of methylene groups (5 and 7 respectively) via melt polycondensation method. Their structural characteristics and thermal properties are presented in detail. (C) 2016 Elsevier B.V. All rights reserved.
