AI Technical Summary

Technical Problem

Current methods for producing thermoset materials are laborious and require multiple steps, often using chlorinated solvents, high temperatures, and long reaction times, making it difficult to achieve degradable and recyclable thermosets from bio-derived sources.

Method used

A one-pot synthesis method using a commercially available bio-sourced monomer, 2,3-dihydrofuran (DHF), which undergoes ring-opening metathesis polymerization (ROMP) followed by photo-cationic polymerization, allowing for spatial and temporal control of crosslinking and enabling degradation and recycling of the thermoset material.

Benefits of technology

This method enables the production of thermosets with tunable mechanical properties that can be degraded and recycled, overcoming the challenges of traditional thermoset synthesis and promoting a circular economy.

Abstract

Thermoset materials and compositions thereof, and methods of making and using same. A thermoset material comprises one or more polymeric group(s) and one or more crosslinking groups. The polymeric group(s) and crosslinking group(s) are least partially formed from the same monomer(s). In various examples, a thermoset material is formed by a method comprising a first polymerization (such as, for example a ring-opening metathesis polymerization (ROMP), an acyclic diene metathesis (ADMET) polymerization, or the like) and a second polymerization (such as, for example, a cationic polymerization, a radical polymerization, or the like). In various examples, a thermoset material (or a composition comprising one or more thermoset material(s) is an article of manufacture, an adhesive, a coating, an insulator, a building material, an elastomeric material, or an additive manufacturing material.
