Bio-based monomers for amide-containing sustainable polymers

Abstract

The field of sustainable polymers from renewable feedstocks is a fast-reviving field after the decades-long domination of petroleum-based polymers. Amide-containing polymers exhibit a wide range of properties depending on the...

Direct Synthesis of Formamide from CO2 and H2O with Nickel–Iron Nitride Heterostructures under Mild Hydrothermal Conditions

“…Amides are an important class of compounds in biological and chemical sciences . They have been used in the manufacture of pharmaceuticals and agrochemicals, and they are also the basis of some versatile synthetic polymers . C–N coupling reaction that produces nitrogenous compounds including amides is one of the most fundamental reactions in the chemical industry. − In life, amide functional groups are ubiquitous moieties in amino acids and the peptide bond .…”

Closed-loop recycling of lignin-based sustainable polymers with an all-hydrocarbon backbone

“…In the age of controlled polymerization, nature-derived molecular biomass has been customized into versatile renewable monomers and building blocks through macromolecular engineering, 12–19 including living polymerization and post-modification strategies ( e.g. , anionic polymerization, 20 atom transfer radical polymerization (ATRP), 21,22 single electron transfer living radical polymerization (SET-LRP), 23–25 reversible addition–fragmentation chain transfer (RAFT) polymerization, 26–29 ring-opening polymerization, 30–32 and click chemistry 33,34 ) as synthesis tools.…”

“…[4][5][6][7][8][9][10] These labile chemical bonds could also lead to undesirable mechanical performance reduction and depressed thermal stability compared with polyolefins. 11 In the age of controlled polymerization, nature-derived molecular biomass has been customized into versatile renewable monomers and building blocks through macromolecular engineering, [12][13][14][15][16][17][18][19] including living polymerization and postmodification strategies (e.g., anionic polymerization, 20 atom transfer radical polymerization (ATRP), 21,22 single electron transfer living radical polymerization (SET-LRP), [23][24][25] reversible addition-fragmentation chain transfer (RAFT) polymerization, [26][27][28][29] ring-opening polymerization, [30][31][32] and click chemistry 33,34 ) as synthesis tools. The inert carboncarbon bonds on their backbone make sustainable polymers strong and tough to compete with the performance of commodity polymers, such as polyolefins manufactured from petroleum chemicals.…”

Biobased Hydroplastic Polymer Networks Enabled by Thiol-Oxazoline Ring-Opening Addition

“…Amide is a moisture-absorbing group; thus, incorporating amide groups to thiol chemistry networks might transform the network into hydroplastics . 2-Oxazoline has a hidden amide functionality that undergoes nucleophilic ring-opening addition with carboxylic acids, phenolic OH, amine, and thiols . Thus, thiol-oxazoline chemistry might be a potential solution to generate amide-containing hydroplastic.…”

“…27 2-Oxazoline has a hidden amide functionality that undergoes nucleophilic ring-opening addition with carboxylic acids, phenolic OH, amine, and thiols. 28 Thus, thiol-oxazoline chemistry might be a potential solution to generate amidecontaining hydroplastic. Herein, methyl vanillate was transformed into oxazoline functionalized monomers (Scheme 1).…”
