Description

Poly[(Isobutylene-Alt-Maleic Acid), Ammonium Salt-Co-(Isobutylene-Alt-Maleic Anhydride)] is a high-performance, water-soluble copolymer designed for demanding industrial applications. This versatile polymer combines the film-forming and dispersing properties of poly(isobutylene-alt-maleic anhydride) with the enhanced solubility and stability of its ammonium salt derivative. It is essential for formulators seeking robust performance in aqueous systems where rheology modification, scale inhibition, or surface activity is required. Key industries that rely on this specialty chemical include water treatment, coatings, adhesives, and personal care.

Application

• Scale and Corrosion Inhibitor in industrial cooling water and boiler water treatment systems.
• Dispersing Agent for pigments, fillers, and inorganic salts in aqueous coatings and construction materials.
• Rheology Modifier and Thickener in water-based adhesives, sealants, and personal care products like hair styling gels.
• Detergent Builder and Anti-redeposition Agent in industrial and institutional cleaning formulations.
• Binder and Film Former in pharmaceutical coatings and agrochemical formulations.
• Processing Aid in paper manufacturing for improved retention and drainage.

Quality Control

Our Poly[(Isobutylene-Alt-Maleic Acid), Ammonium Salt-Co-(Isobutylene-Alt-Maleic Anhydride)] is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assay, viscosity, pH, and residual monomer content. Certificates of Analysis (COA) documenting full specifications are provided with every shipment to guarantee supply reliability and product traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance.
