Preparation and Characterization of Highly Bio‐Based Epoxy Amine Thermosets Derived from Lignocellulosics

“…Currently, over 1.1 million tons of lignin are generated annually by industry with only about 2% used to produce valuable chemicals, demonstrating the vastness of this underutilized resource . Depolymerized lignin has been shown to be a valuable source of substituted phenolics, namely, vanillin and other methoxyphenols, that are produced on industrial scales and can be functionalized into polymer precursors . The high aromatic ring content of lignin imparts rigidity and strength to the biopolymer network.…”

“…[24,25] Depolymerized lignin has been shown to be a valuable source of substituted phenolics, namely, vanillin and other methoxyphenols, that are produced on industrial scales and can be functionalized into polymer precursors. [3,18,19,[26][27][28][29][30][31][32][33][34] The high aromatic ring content of lignin imparts rigidity and strength to the biopolymer network. This same aromaticity is what makes monomer units derived from the depolymerization of lignin so valuable as polymer precursors.…”

Synthesis and Characterization of Epoxy Thermosetting Polymers from Glycidylated Organosolv Lignin and Bisphenol A

“…The monomer approach toward renewable based epoxy thermosets from lignin‐obtained phenols was already intensively investigated. Vanillin‐based epoxy thermosets were described in detail by Caillol and co‐workers . Recently, epoxy thermosets from glycidylated iso‐eugenol were presented .…”

A novel bio‐based phthalonitrile resin derived from catechin: synthesis and comparison of curing behavior with petroleum‐based counterpart

“…Although the commercial application of bio‐based polymers can mitigate environmental impacts, it is important that any bio‐based polymer that is considered as a replacement for petroleum‐based counterparts (such as bisphenol A‐based polymers) exhibits similar properties, including good thermal stability, mechanical strength, processability and compatibility . Therefore, many efforts are currently underway to develop new bio‐based polymers with higher performance values as replacements for polymers currently derived from petroleum‐based feedstocks …”

“…9 Therefore, many efforts are currently underway to develop new bio-based polymers with higher performance values as replacements for polymers currently derived from petroleum-based feedstocks. [10][11][12][13][14][15][16] Advances in industrial biotechnology mean that an increasing number of chemicals are becoming available from renewable resources that can be used as substrates for the synthesis of bio-based polymers with improved properties. [17][18][19] For example, Hong et al have reported a water-soluble epoxy resin prepared from diglycidyl ethers of isosorbide and isosorbide diamine.…”
