The chemical substance known as "PS4," with the CAS number 65322-98-7, is a type of polymer known as polystyrene sulfonate. It is primarily used in various applications, including as an ion-exchange resin and in the treatment of certain medical conditions, such as hyperkalemia, where it helps to lower potassium levels in the blood. PS4 is characterized by its high molecular weight and the presence of sulfonate groups, which impart water solubility and ion-exchange capabilities. The polymer's structure allows it to interact with cations, making it effective in various chemical processes. Additionally, it is generally stable under a range of conditions, although it may be sensitive to extreme pH levels and temperatures. In industrial applications, PS4 is valued for its ability to facilitate the removal of unwanted ions from solutions, making it useful in water treatment and other chemical processes. Safety data sheets should be consulted for handling and disposal guidelines, as with any chemical substance.
