  • Applications

    Ethanol, 2-(ethenylthio)- (CAS 3090-56-0) is primarily used as a reactive monomer and building block in polymer chemistry. It functions as a vinyl sulfide-containing comonomer for radical polymerization, enabling incorporation of thioether linkages into specialty polymers. It is commonly used as a crosslinker or functional monomer in UV-curable coatings and inks, in adhesives and sealants, and in surface-modified polymer formulations, delivering sulfur-containing functionality and improved flexibility. The hydroxyl group on the side chain provides a handle for further chemical modification, making it a practical intermediate for synthesis of specialty polymers, polymer additives, and thiol-ene networks.
