Catalytic Degradation of Thermosetting Polymers in suitable solvents under Atmospheric Pressure: Approaches and Techniques

Unmet Need: The imperative need for chemical recycling of thermosets and thermoset composites

Management of thermosetting polymers and their composites is becoming a serious public concern. The demand for an eco-friendly and economically viable recycling technology that is suitable for industrial scale-up is crucial. Performing chemical recycling under atmospheric pressure is always desirable. WSU inventors invented catalytic degradation of thermosetting polymers and their composites with suitable solvents.

The Technology: Introduced a method for catalytic degradation of the thermosetting materials under atmospheric pressure

WSU inventors introduced a novel approach for catalytic degradation of the thermosetting materials, utilizing an eco-friendly solvent and a low catalyst concentration under atmospheric pressure. Inventors discovered that undisclosed solvents are effective for epoxy decomposition at low concentrations of catalyst under atmospheric pressure. The solvent derivatives ensure the swelling and facilities the decomposition of the thermosetting polymer. Following degradation, the catalytic solution can be recovered and reused for the next reaction.
