Description

2-Methyl-2-Propenoic Acid 2-(Dimethylamino)Ethyl Ester Polymer With Ethenylbenzene, Compd. With (Chloromethyl) Oxirane is a specialized cationic polymer, a key functional material derived from the copolymerization of dimethylaminoethyl methacrylate (DMAEMA) and styrene, subsequently quaternized with epichlorohydrin. This compound matters for its unique combination of cationic charge density and polymeric structure, making it an effective flocculant, retention aid, and charge modifier in demanding aqueous systems. Industrial buyers in water treatment, paper manufacturing, and personal care sectors rely on this polymer for its ability to enhance process efficiency, clarify wastewater, and improve product performance through superior interaction with anionic surfaces.

Application

• Water and Wastewater Treatment: As a highly effective cationic flocculant and coagulant aid for the clarification and dewatering of industrial and municipal sludge.
• Paper and Pulp Industry: Functioning as a retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing paper quality and production speed.
• Personal Care and Cosmetics: Utilized as a conditioning agent and viscosity modifier in hair care products (e.g., shampoos, conditioners) and skincare formulations.
• Textile Processing: Acting as a dye-fixing agent and antistatic agent to improve color fastness and processing performance of synthetic and natural fibers.
• Oilfield Chemicals: Serving as a clay stabilizer and shale inhibitor in drilling fluids to control wellbore stability and fluid loss.
• Adhesives and Sealants: Used as a rheology modifier and tackifier to control the application properties and final bond strength of various adhesive systems.

Quality Control

Our production of this cationic polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as cationic charge density, molecular weight distribution, solids content, and viscosity are strictly monitored. Certificates of Analysis (COA) detailing these specifications are available for every batch upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and should be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from strong alkalis and incompatible organic solvents.
