UCLA researchers in the Departments of Bioengineering, Chemistry and Biochemistry have developed a novel synthetic strategy for the fabrication of biomass-derived polymers incorporating underutilized lignin derivatives.
Polyamide polymers and benzoxazine resins are important materials used in a wide variety of products and manufacturing including the automotive, plastics, and nylons industries. Current methods to produce these polymers and resins utilize a diminishing supply of petroleum-based chemical precursors. While there has been some work identifying biomass-derived materials, they are typically mechanically weaker or have a reduced material lifespan. As the only natural aromatic polymer source, lignin could replace petroleum-derived aromatics in the synthesis of aromatic-based commodity polymeric materials.
Monolignol-based polyamide polymers
Monolignol-based polyamide graft co-polymers of itaconic acid and Tulipalin A
Monolignol-based benzoxazines and polybenzoxazines
This technology utilizes biomass to generate polymers with properties similar to commercially available materials.
Researchers have detailed methods and synthetic schemes for the fabrication of these polymers. Additionally, these polymers have been characterized as having moderate molecular weight and polydispersity, as well as moderately thermostable.
