Function
Sodium styrene sulfonate is a white to yellowish crystalline powder. Relative molecular weight 206.19. Relative density 0.5 (25 ℃). Melting point 330 ℃ (decomposition). It is insoluble in benzene, acetone and carbon tetrachloride, but soluble in water (22.2 at 20 ℃), methanol (5.0 at 20 ℃) and dimethylformamide (8.5 at 20 ℃). This product has vinyl and the induction effect of p-sulfonic group. It has strong reactivity and polymerization ability, so it can be used as a vinyl monomer with sulfonic group.
Product Usage
- Sodium styrenesulfonate is one of the most suitable monomers for the synthesis of water-soluble polymer materials, and its polymer can be used as a dyeing modifier;
