Description

Benzene, Diethenyl-, Polymer With Ethenylbenzene And Ethenylethylbenzene, Aminomethylated is a specialized functionalized polymer resin, chemically modified with aminomethyl groups. This modification is critical for introducing reactive amine functionality into a styrenic polymer backbone, enabling its use as a key intermediate or support material in advanced chemical synthesis. It is primarily required by manufacturers in the life sciences, specialty chemical, and water treatment sectors seeking to develop custom ion-exchange resins, catalyst supports, or polymeric reagents. The product's structure offers a versatile platform for further chemical derivatization.

Application

• As a precursor for the synthesis of strong base anion exchange resins used in water purification and demineralization.
• Acting as a functional polymeric support for immobilizing catalysts, reagents, or enzymes in flow chemistry and industrial catalysis.
• Utilized in the development of chelating resins for selective metal ion recovery and hydrometallurgical processes.
• As a key intermediate for producing adsorbent materials for the removal of specific anions or organic acids from process streams.
• Employed in pharmaceutical synthesis as a solid-phase support for peptide synthesis or scavenger resins.
• Used in R&D for creating specialty polymers with tailored ion-exchange capacity and selectivity profiles.

Quality Control

Our production of Aminomethylated Styrenic Polymer adheres to strict quality protocols to ensure batch-to-batch consistency and performance. Key parameters such as amine capacity, particle size distribution, and crosslinking density are rigorously controlled. A comprehensive Certificate of Analysis (COA) detailing assay, functional group loading, and physical specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material should be stored in a cool, dry place, ideally under an inert atmosphere such as nitrogen to maintain reactivity and prevent degradation. Recommended storage temperature is 2-25°C. Keep away from strong oxidizing agents.
