“…In contrast, 18 and 19 were symmetrical and thus produced homopolymers 21 and 22, respectively, that were the equivalent of In subsequent reports by the Hodge group, a comparison of the two most common catalysts used in ED-ROMP reactions was performed. 56,57 The results showed that 1 and 2 were similarly effective in ED-ROMP of various strainless macrocycles, however, the efficiency of 2 in the CDP was superior. The authors stressed that when 2 is used to initiate such reactions, that ED-ROMP products are likely to have a series of closely related repeat units, i.e., homologs as a result of olefin isomerization (migration).…”

“…ROM, as the name implies, opens rings to afford new, derivatised small molecules featuring two olefin fragments. When no cross-partner is present, homopolymerisation is favoured, as in ROMP (from the ring form) or ADMET (from a diolefin monomer); these fields have been extensively reviewed [4][5][6][7][8][9][10] and fall outside the scope of this review. For RCM and CM, however, the reactions have been developed with small molecule synthesis in mind and while they are well established in organic synthesis, [11][12][13] much less work has been reported in the application of these reactions to polymer chemistry.…”

“…The resulting dicarboxylic acids were polymerized with their corresponding diols (obtained after reduction) to yield PE-20,20 and PE-26,26. Besides, linear long aliphatic chain polyesters have been largely provided by ADMET polymerization 251,521,[523][524][525] of estercontaining α,ω-dienes, themselves prepared from fatty acids (Figure 96). Most of these studies conducted the hydrogenation of the resulting unsaturated polyesters with the aim of mimicking polyethylene structure.…”

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...
