Description

Poly(4-Vinylphenol-Co-2-Hydroxyethyl Methacrylate) is a high-performance copolymer designed for advanced material science applications, combining the phenolic functionality of poly(4-vinylphenol) with the hydrophilic, crosslinkable properties of 2-hydroxyethyl methacrylate. This unique chemical architecture makes it an essential component for formulating specialty polymers with tailored surface properties, adhesion, and reactivity. It is particularly valuable for industries requiring precision-engineered resins, such as advanced coatings, photoresists, and specialty adhesives.

Application

• Photoresist Formulations: Acts as a key polymeric binder in advanced photoresists for semiconductor and microelectronics manufacturing, offering excellent film-forming properties and etch resistance.
• Specialty Coatings & Inks: Used as a functional additive or primary resin in high-performance coatings, printing inks, and overprint varnishes to enhance adhesion, gloss, and chemical resistance.
• Adhesives & Sealants: Serves as a base polymer for formulating structural and pressure-sensitive adhesives, providing strong bonding to diverse substrates and improved cohesion.
• Ion-Exchange & Chelating Resins: Utilized as a precursor or functional component in the synthesis of resins for water treatment, metal recovery, and catalysis due to its phenolic hydroxyl groups.
• Biomedical & Pharmaceutical Materials: Employed in the development of drug delivery matrices, biosensor coatings, and biocompatible hydrogels, leveraging its tunable hydrophilicity and reactivity.
• Composite Materials: Functions as a compatibilizer or surface modifier in polymer composites and nanocomposites to improve interfacial adhesion and dispersion of fillers.

Quality Control

Our Poly(4-Vinylphenol-Co-2-Hydroxyethyl Methacrylate) is manufactured under strict quality management systems. Each batch undergoes rigorous testing to ensure consistency in monomer ratio, molecular weight distribution, residual monomer content, and functional group concentration. Certificates of Analysis (COA) detailing specifications such as purity, viscosity, and thermal properties are provided with every shipment to guarantee compliance with your technical 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 material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent clumping or property changes. Keep away from strong oxidizing agents.
