What is Sodium p-styrenesulfonate Cas 2695-37-6?

Sodium p-styrenesulfonate (CAS 2695-37-6) is an important organic compound. Abbreviated as SSS. Sodium 4-vinylbenzenesulfonate molecules contain vinyl and sulfonic acid groups, which have high reactivity and can undergo polymerization reactions. They can be copolymerized with other monomers to form various high-molecular polymers. Meanwhile, sodium p-styrenesulfonate has good thermal stability and will not decompose below 300℃.
