Bundle Formation in Poly(styrene) sulfonate Brushes
Linear polyions in solution repel each other and form strongly structured fluids. Thus, Bragg peaks are detected with scattering methods [1]. At high polyion concentrations cp, their nearest neighbor distance d scales with the square root of cp. To explain this relationship, de Gennes et al. [2] proposed a detailed model of flexible polyelectrolytes at low ionic strength and high polyion concen...
متن کاملSodium polystyrene sulfonate (Kayexalate) aspiration
In this short report we illustrate a case of extensive sodium polystyrene sulfonate (SPS) aspiration as an immediate cause of death in a terminally ill patient. SPS is a cation exchange resin utilized to decrease potassium levels in patients with renal failure. When administered rectally in conjunction with sorbitol, colonic necrosis and perforation have been documented. On the other hand, oral...
متن کاملAdsorption of Polystyrene Sulfonate to the Air Surface of Water by Neutron Reflectivity
The adsorption of the strong polyelectrolyte polystyrene sulfonate (PSS) to the air surface of dilute aqueous solutions was investigated as a function of molecular weight and salt concentration. Detailed segment profiles of the deuterated polymer were determined by neutron reflection. Surface activity was also examined through surface tension measurements. In general, the segment profiles are c...
متن کاملPalatability and physical properties of potassium-binding resin RDX7675: comparison with sodium polystyrene sulfonate
BACKGROUND Hyperkalemia is a potentially life-threatening condition that patients with heart failure or chronic kidney disease, especially those taking renin-angiotensin-aldosterone system inhibitors, are at high risk of developing. Sodium polystyrene sulfonate (SPS), a current treatment, binds potassium within the gastrointestinal tract to reduce potassium absorption. However, poor palatabilit...
متن کاملHypernatremia in a patient treated with sodium polystyrene sulfonate
Severe hyperkalemia requires urgent medical attention and correction in order to prevent arrhythmic complications. Sodium polystyrene sulfonate (SPS) is a cation exchange resin commonly used in the management of hyperkalemia. A recent review raised concerns regarding its effectiveness and potential adverse effects. Hypernatremia in adults in the setting of sodium polystyrene sulfonate therapy h...
