Description

Aminophenyl-Polyacrylamide is a functionalized polymer derivative that combines the properties of polyacrylamide with the reactivity of an aromatic amine group. This unique structure makes it a valuable intermediate and functional material for advanced chemical synthesis and material modification. It is particularly sought after by industries involved in specialty polymer production, water treatment, and the development of functional coatings and adhesives.

Application

• Functional Polymer Synthesis: Acts as a key monomer or co-monomer for creating polymers with specific amine-based reactivity, used in ion-exchange resins, chelating agents, and flocculants.
• Water Treatment Chemicals: Utilized in the formulation of high-performance flocculants and coagulant aids for industrial wastewater and municipal water purification processes.
• Enhanced Oil Recovery (EOR): Serves as a component in polymer flooding formulations to improve the viscosity and sweep efficiency of injected water in oil reservoirs.
• Paper Manufacturing: Used as a wet-strength additive and retention aid to improve paper quality and production efficiency.
• Textile & Leather Processing: Functions as a dye-fixing agent, tanning auxiliary, and finishing agent to enhance color fastness and material properties.
• Adhesive & Coating Formulations: Incorporated to improve adhesion, cross-linking density, and chemical resistance in specialty adhesives and protective coatings.
• Biomedical & Research Applications: Employed in the development of hydrogels, drug delivery systems, and as a substrate for enzyme immobilization in biotechnology.

Quality Control

Our Aminophenyl-Polyacrylamide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and functional group content. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, residual monomer content, and viscosity. Our quality commitment aligns with industrial best practices, and we can support compliance documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To prevent moisture uptake and potential degradation, ensure the container is sealed immediately after use and consider storage under a dry inert atmosphere for long-term stability.
