Abstract

Homopolymers and copolymers derived from 2,5-furandicarboxylic acid have been extensively studied for their potential in the development of sustainable plastics. This research definitely spotlighted the synthesis of poly(ethylene-co-butylene 2,5-furandicarboxylate) copolymer via the two-step melting polycondensation with various ethylene glycol/1,4-butanediol molar ratios. The structural characterization of the obtained biobased copolymer was carried out by ATR-FTIR and 1H NMR. The average molecular weight of the obtained copolymer was determined by the intrinsic viscosity measurements. It was found that ethylene glycol was preferentially incorporated into the copolymer structures when the molecular weight of the products was not high enough (>18000). The decomposition of two types of monomer units of the obtained copolymer was proven through the degradation two-step process by TGA measurements.

Highlights

Polyesters based on 2,5-furandicarboxylic acid (FDCA) have received the significant attention of many scientists in an effort to replace the dominant petroleum-based polymers in plastic engineering [1, 2]
There are a considerable number of research publications relating to synthesis and characterization of copolymers based on FDCA block in combination with conventional homopolymers [10]
There are no significant differences between the Fourier transform infrared spectroscopy (FT-IR) spectra of the copolymer products and the PEF and PBF homopolymers

Summary

Introduction

Polyesters based on 2,5-furandicarboxylic acid (FDCA) have received the significant attention of many scientists in an effort to replace the dominant petroleum-based polymers in plastic engineering [1, 2]. FDCA has drawn a special interest recently since its derived polymers have series of comparable properties with the corresponding polymers synthesized from terephthalic acid in terms of structures, crystalline, thermal and mechanical behaviors, sorption, and transportation of carbon dioxide, water, oxygen, etc. There are a considerable number of research publications relating to synthesis and characterization of copolymers based on FDCA block in combination with conventional homopolymers [10]. According to many recent reports in the literature, the ambitions of studying FDCA-based copolymers in particular have focused on two major objectives: controlling and enhancing polymers’ desired characteristics and combining polymers’ advantages of biosourced syntheses and biodegradation
