Description

Polystyrene Polyamine Copolymer is a synthetic polymer resin featuring a backbone of polystyrene with pendant polyamine functional groups. This unique structure provides excellent chelating and ion-exchange properties, making it a valuable material for selective binding and purification processes. It is primarily utilized in water treatment, pharmaceutical manufacturing, and as a specialized adsorbent in chemical synthesis. The compound is commercially available under various trade names and is identified by CAS No. 75734-81-5.

Application

• Water Treatment & Purification: Acts as a selective ion-exchange resin or chelating agent for the removal of heavy metal ions (e.g., copper, lead, mercury) from industrial wastewater and process streams.
• Pharmaceutical Intermediate Purification: Used in the purification of active pharmaceutical ingredients (APIs) and fine chemicals by selectively binding impurities or catalysts.
• Catalyst Support & Recovery: Serves as a solid support for immobilizing transition metal catalysts, facilitating their recovery and reuse in organic synthesis.
• Chromatography & Separation Science: Employed as a stationary phase in chromatographic columns for the analytical and preparative separation of complex mixtures.
• Polymer Modification & Additive: Incorporated into polymer blends to enhance properties such as adhesion, dyeability, or antistatic performance.
• Laboratory Research & Development: Utilized as a specialized reagent in R&D for developing new separation, catalysis, and sensing technologies.

Quality Control

Our Polystyrene Polyamine Copolymer is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as amine capacity, particle size distribution, and chemical stability. While specific grades may be tailored for applications like pharmaceutical support or heavy metal removal, we ensure compliance with relevant industry guidelines. A comprehensive Certificate of Analysis (COA) detailing assay, functional group content, and physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored in a cool, dry place at room temperature (15-25°C/59-77°F). To prevent moisture uptake and potential clumping, the container should be kept sealed when not in use and stored in a low-humidity environment. Avoid prolonged exposure to high temperatures.
