High Performance Bio-Based Monomers for Thermoset Resin

Drexel University and the US Army seek a partner to license and commercialize bio-based monomers like isosorbide methacrylate (IM) that can improve performance characteristics of thermoset resins. IM monomers can be manufactured as a neat formulation or in economically blended IM-vinyl ester or IM-polyester resins.

The Technology: 

The Army Research Laboratory (ARL) and Drexel University have developed and tested patent-pending vinyl ester and unsaturated polyester composite resins based on non-petroleum celluloses or carbohydrates. These vinyl ester (VE) resins offer significantly higher glass transition temperatures (Tg) than commercial VE resins. In addition, their mechanical performance is comparable to that of many high temperature epoxies, but at a fraction of the cost. The resins offer extremely low viscosity and can be used without reactive diluents, such as styrene, without sacrificing quality. The resins can also be used as an additive to reduce viscosity and/or improve thermo-mechanical traits in other composites.


• Affordable High Performance: Thermal and mechanical properties similar to those of expensive high temperature epoxy systems from an inexpensive vinyl ester platform
• Superior Vinyl Esters: Extremely low viscosity (5 cP with 35% styrene/157 cP neat), high stiffness, and higher temperature (Tg > 240oC) window compared to other vinyl esters
• Bio-Based: Anhydrosugar base is structurally desirable and from renewable, non-petroleum materials
• Versatile: Applicable as a primary monomer or performance additive
• Easy Scale-up: Can produce a high quality IM-resin blend without steps to purify/remove-solvent from IM

The Opportunity: 

• US 2014/0249285, US 2016/0222149, and international filings are available for license
• Potential for collaboration with ARL and Drexel researchers
