Description

2-Propenoic acid, polymer with ethenylbenzene and 2-propenamide, commonly referred to as a styrene-acrylamide-acrylic acid terpolymer, is a high-performance synthetic polymer engineered for demanding industrial applications. This versatile copolymer combines the structural strength of styrene, the hydrophilic functionality of acrylamide, and the anionic character of acrylic acid to deliver exceptional performance as a flocculant, thickener, and binder. It is a critical raw material for water treatment facilities, paper manufacturers, and the construction industry, where its ability to modify rheology and promote particle aggregation is highly valued. The compound is supplied under CAS No. 27083-59-6.

Application

• Water Treatment: Primary application as a high-efficiency flocculant and coagulant aid for clarifying industrial wastewater, municipal water, and process water.
• Paper Manufacturing: Used as a retention and drainage aid, as well as a dry strength agent to improve paper quality and production efficiency.
• Construction & Cement: Acts as a rheology modifier and superplasticizer in cementitious materials, improving workability and reducing water content.
• Enhanced Oil Recovery (EOR): Employed as a viscosifier in polymer flooding operations to improve oil displacement and recovery rates.
• Textile & Leather Processing: Functions as a sizing agent, finishing chemical, and dye-fixing auxiliary to enhance fabric properties.
• Mining & Mineral Processing: Utilized in solid-liquid separation processes, such as tailings dewatering and mineral concentrate settling.
• Paints & Coatings: Serves as a thickener, dispersant, and stabilizer in aqueous formulations to control viscosity and pigment suspension.
• Adhesives & Sealants: Provides binding strength and modifies the adhesive properties in various industrial and construction adhesives.

Quality Control

Our styrene-acrylamide-acrylic acid terpolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including intrinsic viscosity, solid content, ionic character, and residual monomer levels to ensure consistent performance and reliability in your process. Certificates of Analysis (COA) documenting these specifications are available upon request. We adhere to relevant ISO standards and can support compliance requirements for global markets.

Storage

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