Lignin is a copious pulp and paper industry waste product that has the potential to be a vital next-generation biorefinery feedstock that could yield valuable macromolecular and low molecular weight aromatic chemicals when strategically depolymerized.
The high aromatic content found in lignin would be ideal for the development of high-performance, bio-based polymers for a wide range of applications since the incorporation of aromaticity to the chemical structure of a polymer is known to drastically improve its strength and increase its glass transition temperature.
Methacrylated lignin model compounds synthesized and employed as alternative, bio-based monomers for use in high-performance polymers are presented. Specifically, methacrylated versions of vanillin, guaiacol, eugenol, phenol, creosol, 4-propylguaiacol, catechol, and 4-methylcatechol were incorporated either individually as potential styrene replacements or as mixtures into vinyl ester resins.
Monomer properties as well as structure- property relationships of the resins and polymers are also presented.
