Description

2-Propenoic Acid, 2-Methyl-, 2-(Dimethylamino)Ethyl Ester, Homopolymer, Acetate is a cationic polymer derived from the quaternization of poly(DMAEMA) (poly(2-(dimethylamino)ethyl methacrylate)). This material is valued for its strong positive charge and film-forming properties, making it an effective flocculant, retention aid, and conditioning agent. It is primarily utilized in water treatment, paper manufacturing, and personal care formulations where charge interaction and viscosity modification are critical.

Application

• Water Treatment: Acts as a highly effective cationic flocculant for clarifying industrial wastewater and municipal water by agglomerating suspended solids and organic matter.
• Paper & Pulp Industry: Serves as a retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing production efficiency and paper quality.
• Personal Care & Cosmetics: Used as a conditioning polymer in hair care products (shampoos, conditioners) and skincare formulations to provide film-forming, detangling, and softness benefits.
• Textile & Leather Processing: Functions as a dye-fixing agent and softening auxiliary to improve color fastness and hand feel of fabrics and leathers.
• Adhesives & Coatings: Employed as a rheology modifier and dispersant to stabilize formulations and control application properties.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as a shale inhibitor and viscosity control agent.
