Abstract

In this work, novel polyester amides (PEAs) based on renewable poly(propylene furanoate) (PPF) were prepared via traditional melt polycondensation utilizing a preformed symmetric amido diol (AD) containing two internal amide bonds.

Highlights

Over the last decades, rising concentrations of greenhouse gases and over-exploitation of finite resources made it apparent that our linear economy based on petrochemicals needs to be replaced in the medium term with a circular bioeconomy relying on renewable resources.[1,2,3]
5-hydroxymethylfurfural, holds a prominent position as a chemical platform accessible from cellulose,[7] which can be utilized for many different applications – from the synthesis of alkaloids,[8] to the production of liquid hydrocarbon fuels and fuel additives derived from hydrogenated hydroxymethylfurfural (HMF) structures.[9]
We have recently demonstrated that long chain polyester amides (PEAs) containing furan moieties can be obtained through traditional melt polycondensation.[29]

Summary

Introduction

Over the last decades, rising concentrations of greenhouse gases and over-exploitation of finite resources made it apparent that our linear economy based on petrochemicals needs to be replaced in the medium term with a circular bioeconomy relying on renewable resources.[1,2,3] As a result, alternative routes. 5-hydroxymethylfurfural, holds a prominent position as a chemical platform accessible from cellulose,[7] which can be utilized for many different applications – from the synthesis of alkaloids,[8] to the production of liquid hydrocarbon fuels and fuel additives derived from hydrogenated hydroxymethylfurfural (HMF) structures.[9] one of the most studied applications for furan derivatives is the production of thermoplastic polyesters as an alternative to polyesters from aromatic dicarboxylic acids.[10,11,12,13] Due to the heteroatom present in the structure of the furan ring, these polyesters present excellent gas barrier properties and are considered a possible replacement of terephthalic acid based polyesters that currently dominate the food packaging market.[12,14,15].
