Description

Poly(2-Ethylacrylic Acid) is a synthetic, high molecular weight polymer derived from 2-ethylacrylic acid, known for its pH-responsive behavior and carboxylic acid functionality. This property makes it a valuable material for creating smart delivery systems and responsive surfaces in advanced industrial applications. It is particularly sought after by formulators and researchers in the pharmaceutical, biomedical, and specialty coatings sectors who require precise control over material properties in changing environments.

Application

• pH-Responsive Drug Delivery Systems: Used as a key polymer in the fabrication of micelles, liposomes, and nanoparticles that release therapeutic agents in response to specific pH conditions, such as in tumor microenvironments.
• Biomedical & Tissue Engineering: Serves as a functional component in hydrogels and scaffolds where its swelling/deswelling behavior can be controlled for cell encapsulation or controlled release of bioactive molecules.
• Smart Coatings & Films: Incorporated into coatings for sensors, membranes, and surfaces that change permeability, adhesion, or wettability in response to pH changes.
• Adhesives & Sealants: Acts as a functional additive to modify the rheological properties and environmental responsiveness of industrial adhesive formulations.
• Research & Development: A critical raw material for academic and industrial R&D focused on stimuli-responsive polymers, polymer chemistry, and novel material science.
• Personal Care & Cosmetics: Potential use in advanced cosmetic formulations for controlled release of active ingredients.

Quality Control

Our Poly(2-Ethylacrylic Acid) is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, acid value, and purity. Certificates of Analysis (COA) detailing key parameters are provided with every shipment to support your quality assurance and regulatory needs.

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 material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent caking or property alteration. Keep away from strong bases and oxidizing agents.
