Polystyrene sulfonate

Polystyrene sulfonate (pronunciation: /ˌpɒliˈstaɪriːn ˈsʌlfəneɪt/) is a type of polymer used primarily in medicine for its ability to bind potassium ions.

Etymology

The term "polystyrene sulfonate" is derived from its chemical structure. "Poly" is from the Greek word "polus" meaning "many", "styrene" is a derivative of the Greek word "styrax" meaning "resin", and "sulfonate" refers to the presence of a sulfonate group in the polymer chain.

Medical Use

Polystyrene sulfonate is used in the treatment of hyperkalemia, a condition characterized by elevated levels of potassium in the blood. It works by exchanging its sodium ions for potassium ions in the large intestine, thereby reducing the overall potassium levels in the body.
