使用Poly(sodium 4-styrenesulfonate) used as an anionic polyelectrolyte, suspending aid for particulates and scale control agent for water treatment. It is an effective antistatic and specialty dispersant, protective colloid for oil-in-water emulsions and viscosity modifier in aqueous-based adhesives.
一般的な説明Poly (sodium 4-styrenesulfonate) (PSS) a cation exchange polyelectrolyte. PSS may be used to produce mechanically stable and very reproducible coatings.
純化方法Purify the polymer by repeated precipitation of the sodium salt from an aqueous solution by MeOH, with subsequent conversion to the free acid by passage through an Amberlite IR-120 ion-exchange resin. [Kotin & Nagasawa J Am Chem Soc 83 1026 1961.] Recrystallise it from EtOH. Alternatively purify it by passage through cation and anion exchange resins in series (Rexyn 101 cation exchange resin and Rexyn 203 anion exchange resin), then titrated it with NaOH to pH 7. The sodium form of polystyrenesulfonic acid is precipitated by addition of 2-propanol. Dry it in a vacuum oven at 80o for 24hours, and finally increasing to 120o before to use. [Kowblansky & Ander J Phys Chem 80 297 1976.]
