Used as a sulfur-containing crosslinking agent in polymer chemistry, particularly in the synthesis of specialty rubbers and elastomers. Its thiol and ether functional groups enable efficient radical-mediated crosslinking, improving thermal stability and mechanical properties of the resulting materials. Commonly applied in the development of high-performance sealants, adhesives, and coatings where enhanced durability and chemical resistance are required. Also investigated as a modifier in vulcanization processes for synthetic rubber, offering better control over cure kinetics and network formation.
