“…This is also reflected by the low values of $\overline L _{\rm n} ({\rm T})$ and $\overline L _{\rm n} ({\rm F})$ . These copolyesters exhibited the same microstructure as their homologs obtained by interchange reaction between the corresponding PET and PEF homopolyesters 26…”

“…The synthesis of PET copolyesters can be carried out by melt polycondensation between monomers,18, 19 by ester interchange between homopolyesters,20–23 or by reaction of PET with lactones or cyclic oligoesters 24, 25. In a previous work, we described the synthesis of furanic‐terephthalic copolyesters by the high temperature ester interchange reaction between high molar mass PET and poly[ethylene 5,5′‐isopropylidene‐bis(2‐furoate)] (PEF) 26. A kinetic study showed that the block copolyesters formed at the beginning of reaction slowly rearranged to random copolyesters after 2 h reaction.…”

5,5′‐Isopropylidene‐bis(ethyl 2‐furoate), a monomer prepared from bio‐based ethyl 2‐furoate, was reacted with dimethyl terephthalate and ethan‐1,2‐diol (ED) by melt polycondensation in order to obtain copolyesters containing both terephthalate and furoate units. The conventional two‐step method involving (i) the formation of a hydroxyethyl‐terminated oligomer by reaction of starting diester mixture with excess ED and (ii) a polycondensation step with elimination of ED was used to obtain high molar mass copolyesters. Copolymers of various compositions were synthesized and characterized by 1H NMR, DSC, and TGA. For all compositions, the degree of randomness, determined by 1H NMR, was close to 1, reflecting a random distribution of terephthalic and furanic ester units in polymer chains. The resulting materials are amorphous polymers (Tg = 70–80 °C) with good thermal stability.

Synthetic polymers are of major interest in the chemical industry, with a world production superior to 350Mt in 2016. They find applications in all the branches of industry, from packaging films to the stateof-the-art materials for sports and leisure activities, construction and aerospace industry or medical applications. Half of the amount of molecules produced by the petrochemical industry thus finds itself incorporated in the elaboration of polymer materials. With a production of 160Mt / year, ethylene can be considered as the major example of petroleum-based monomers. Green Chemistry introduced in 1998 by Anastase et al. (refer to Chapter 1 of this book), aims at providing solutions to reduce environmental impacts of our society. More precisely, this pursue of a more sustainable chemistry consists in using a source of renewable carbon to both reduce the dependence on fossil resources and thus stabilize greenhouse gas emissions (in particular CO 2 ) at the end of life. The use of renewable resources is of major interest in the elaboration of bio-sourced polymers. By using them, it is possible to mimick the fossil-based polymers -drop-in structures such as biopolyethylene-or to design new chemical structures, such as poly(lactic acid), PLA. Nowadays, the vegetal-based chemistry (renewable resources) mobilizes less than 0.5 % of arable land in the world. Some reminders of the definitions of the terms biomass, biopolymer, biodegradable polymer, bio-sourced polymer, bioplastic, biorefinery may be necessary: Biomass: material of biological origin (elaborated by alive bodies) with the exception of the materials of geological or fossil formation.Biopolymer: polymer developed by alive bodies, extracted from the biomass. Examples: polysaccharides, proteins, bacterial polymers.Biodegradable polymer: polymer the main degradation mechanism of which can be biotic, by enzymatic way. Under the action of micro-organisms and in the presence of oxygen (aerobic conditions), the organic compound decomposes totally within few months into carbon dioxide, water and mineral salts, with the appearance of a new biomass; in the absence of oxygen (anaerobic conditions), the organic compound decomposes totally within few months into carbon dioxide, methane, mineral salts and creation of a new biomass.Bio-sourced (or bio-based) polymer: synthetic polymer partially (generally > 20 %) or totally obtained from by-products stemming from the biomass. The bio-sourced character of a polymer can be determined in particular from its content in C14, according to the standard ASTM D6866. For the materials of totally fossil origin, the content in C14 is null.Bioplastic: term of popularization which indicates a 'biobased plastic' (restricted definition) and/or biodegradable (wider definition).Biorefinery: by analogy with a classic refinery, which works from fossil resources, a bio-refinery handles biomasses to produce, according to the cases, energy, fuels, materials, chemical and polymer products and/or animal and human feed. Today, two biopolymers ac...
