Description

2-Propenoic Acid, 2-Methyl-, Potassium Salt, Polymer With Diethenylbenzene is a cross-linked, potassium-based polyacrylate resin. This specialized polymer is valued for its high ionic capacity and robust physical structure, making it an effective ion-exchange material and superabsorbent. It is primarily utilized in water treatment, chromatography, and specialty chemical synthesis where controlled ion exchange or moisture management is required. Our supply ensures consistent quality and reliable performance for industrial applications.

Application

• Ion-Exchange Chromatography: Used as a stationary phase for the separation and purification of proteins, peptides, and other biomolecules.
• Water Treatment & Softening: Effective in removing calcium, magnesium, and other metal ions from process water and industrial effluents.
• Catalyst Support: Serves as a solid support matrix for catalysts in various organic synthesis reactions.
• Controlled-Release Systems: Employed in agricultural and pharmaceutical formulations for the slow release of active ingredients.
• Specialty Absorbents: Utilized in applications requiring controlled absorption of aqueous solutions or specific ions.
• Analytical Sample Preparation: Acts as a solid-phase extraction (SPE) medium for concentrating or cleaning up analytes.

Quality Control

Our production of 2-Propenoic Acid, 2-Methyl-, Potassium Salt, Polymer With Diethenylbenzene adheres to strict quality management protocols. Each batch undergoes rigorous testing for critical parameters including ionic capacity, particle size distribution, moisture content, and chemical stability to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) documenting purity, performance, and physical characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials such as strong acids.
