Use: Styrene sodium is widely used as the mediates of the interaction between organic and inorganic compounds in many production process because of its unique chemical structure. Styrene sodium has the following characteristics: (1) Very low toxicity compared with other sulfonic acid materials. (2)Higher reactivity (3) good interpolymerization, (4) No decomposed in water. Used in oil field as scale inhibitor, flocculating agent and dewatering agents,

Sodium p-styrene sulfonate
