Description

Butanoic acid, 3-oxo-, 2-[(2-methyl-1-oxo-2-propenyl)oxy]ethyl ester, polymer with 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonic acid, 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonic acid monosodium salt and methyl 2-propenoate is a specialized, high-performance copolymer designed for advanced material science applications. This product matters because it combines multiple functional monomers to deliver unique properties such as excellent dispersancy, binding capacity, and stability in challenging formulations. It is primarily needed by industries developing high-performance coatings, adhesives, and specialty polymer composites where precise rheological control and compatibility are critical.

Application

• Dispersant and Stabilizer in high-solids industrial coatings and paints.
• Rheology Modifier and binder in advanced adhesive and sealant formulations.
• Compatibility Aid in polymer blends and composite materials.
• Functional Additive in water treatment chemicals and scale inhibition formulations.
• Surface Treatment Agent for pigments and fillers to improve dispersion in liquid media.
• Key Component in the synthesis of specialty ion-exchange resins or membranes.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent performance, including verification of monomer conversion, molecular weight distribution, and functional group content. Certificates of Analysis (COA) detailing key specifications are provided with each shipment to guarantee traceability and compliance with your formulation requirements.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent moisture absorption, which may affect product performance.
