Bio-based aromatic polyesters and copolyesters by ring opening polymerization

Abstract

In this work, the synthesis of both c(BF)n and c(BT)n has been performed using the high dilution cyclization technique and these cycles have been then used for the preparation of the homopolyesters PBF and PBT, as well as of a series of poly(butylene 2,5-furandicarboxylate-co-terephthalate) (coPBFxTy) with a wide range of compositions (Fig. 1). Results are compared with those obtained from similar copolyesters prepared by melt polycondensation, which have been recently reported
