Description

Benzene,Diethenyl-,Polymer With Ethenylbenzene,Chloromethylated,2-(Dimethylamino)Ethanol-Quaternized is a quaternary ammonium functionalized polymer, a specialized cationic polyelectrolyte derived from styrene-divinylbenzene. This compound matters for its strong cationic charge density and film-forming properties, making it a highly effective agent for flocculation, charge neutralization, and surface modification. Industries requiring advanced water treatment, paper manufacturing, or specialty coatings will find this polymer essential for process efficiency and product performance.

Application

• Water & Wastewater Treatment: Acts as a primary coagulant aid and flocculant for the removal of suspended solids, organic matter, and clarification in industrial effluent streams.
• Paper & Pulp Industry: Used as a retention and drainage aid, as well as a fixing agent for anionic trash control to improve paper quality and machine runnability.
• Oilfield Chemicals: Serves as a clay stabilizer and shale inhibitor in drilling fluids to prevent formation damage and improve wellbore stability.
• Textile Processing: Functions as a dye-fixing agent and antistatic agent to improve color fastness and handleability of synthetic fibers.
• Personal Care & Cosmetics: Utilized as a conditioning agent and viscosity modifier in hair care and skincare formulations for enhanced texture and performance.
• Industrial Coatings & Adhesives: Imparts cationic character for improved adhesion to anionic substrates and acts as a dispersant for pigments and fillers.
• Biotechnology & Pharmaceuticals: Employed in downstream processing for the purification and recovery of biomolecules through ion-exchange and flocculation techniques.

Quality Control

Our production of this quaternary ammonium polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as cationic charge density, viscosity, solids content, and residual monomers are strictly monitored. Certificates of Analysis (COA) detailing all relevant specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
