SPINOMAR® NaSS (CAS 2695-37-6)
SPINOMAR NaSS is a registered trademark for Tosoh Corporation’s patented hemihydrate form of sodium styrenesulfonate.
This novel product form exhibits better stability, reduced polymerization in storage and reduced lumping in storage than standard grades. The hemihydrate form is covered by U.S. Patent 5,898,083 and Japan Patent JP36012222.
Sodium Styrenesulfonate
Sodium styrenesulfonate (NaSS) is a highly reactive vinyl monomer containing a hydrophilic sulfonate group. Significant advantages of NaSS as compared with other monomers are low toxicity and high thermal stability. NaSS is widely used to improve dyeability of acrylic and polyester fibers. Other applications include reactive emulsifiers for water-borne coatings and anti-static agents for textiles, plastics, and papers. Fields of application include water treatment, photography and paper manufacturing.
