Description

2-Propenoic Acid, 2-Methyl-, 2-(Dimethylamino)Ethyl Ester, Polymer With Diethenylbenzene And Methyl 2-Methyl-2-Propenoate is a specialized cationic copolymer designed to deliver unique performance characteristics in demanding formulations. This polymer is valued for its ability to modify surface properties, enhance adhesion, and provide controlled release functionality. It is a critical raw material for manufacturers in the pharmaceutical, personal care, and advanced coating industries seeking to develop high-performance products with specific interactive properties.

Application

• Pharmaceutical Excipient: Used as a film-forming agent, taste-masking polymer, or controlled-release matrix in tablet and capsule formulations.
• Personal Care & Cosmetics: Functions as a cationic conditioning agent in hair care products (shampoos, conditioners) and a film-former in skin care and color cosmetics.
• Industrial Coatings & Adhesives: Serves as a key component in specialty coatings, primers, and adhesives where enhanced substrate wetting, adhesion promotion, and corrosion resistance are required.
• Water Treatment: Acts as a flocculant or clarifying agent in water purification processes due to its cationic charge and polymer chain structure.
• Paper & Textile Manufacturing: Utilized as a retention aid, drainage aid, or surface sizing agent in paper production, and as a fabric softener or dye-fixing agent in textiles.
• Advanced Material Science: Employed in the research and development of drug delivery systems, ion-exchange resins, and specialty membranes.

Quality Control

Our production of this specialty copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including monomer ratio, molecular weight distribution, residual monomer content, and ionic charge density to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing these specifications are provided and available upon request. We support compliance with relevant frameworks including GMP, ICH Q7, and REACH for applicable grades.

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). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect performance.
