What are the physical and chemical properties of Poly(2-phenylethenesulfonic acid compound with 2,3-dihydrothieno[3,4-b][1,4]dioxine) (CAS: 155090-83-8)?

Poly(2-phenylethenesulfonic acid compound with 2,3-dihydrothieno[3,4-b][1,4]dioxine) is a polymer with a high molecular weight, typically above 10,000 g/mol. It exhibits excellent solubility in polar solvents such as water and alcohols. Chemically, it is highly reactive, particularly towards nucleophiles and reducing agents. Its crystalline form is stable under normal conditions, but it can be dissolved in water to form a conductive solution.
