Inefficient chemical pathways for integrating sulfur into stable polymer architectures. Overcoming this limitation enables the production of high-refractive index materials with controlled thermal properties.

Conventional polyurethane synthesis relies on hazardous isocyanates that react prematurely with environmental humidity. Utilizing cyclic monothiocarbonates enables high-performance thermosets without toxic precursors or moisture-induced defects.

Difficulty in accessing high-purity cyclic carbonate precursors with reactive exocyclic groups. Streamlining this synthesis reduces production costs and enables functional polymer architectures.

Conventional polyurethane synthesis relies on hazardous isocyanate chemistry which poses severe health and environmental risks. Utilizing cyclic monothiocarbonates provides a non-toxic pathway to high-performance networks.
