Description

Poly(1-Vinylpyrrolidone)-Graft-(1-Hexadecene) CAS NO 63231-81-2 is a specialized amphiphilic graft copolymer, combining the hydrophilic properties of polyvinylpyrrolidone (PVP) with the hydrophobic characteristics of a hexadecene side chain. This unique molecular architecture provides exceptional performance as a compatibilizer, stabilizer, and rheology modifier in complex formulations. It is particularly valuable for industries requiring advanced surface modification and controlled release mechanisms. Key sectors that utilize this polymer include pharmaceuticals, advanced coatings, personal care, and specialty adhesives.

Application

• Pharmaceutical Formulations: Acts as a stabilizer for nanoparticles and liposomes, and as a matrix for controlled drug delivery systems.
• Advanced Coatings & Inks: Serves as a dispersant and rheology modifier for pigments, enhancing stability and application properties.
• Personal Care Products: Used in hair styling gels, creams, and sunscreens as a film-forming agent and stabilizer for emulsions.
• Adhesives & Sealants: Functions as a tackifier and compatibility enhancer in pressure-sensitive and structural adhesives.
• Agricultural Chemicals: Employed as an adjuvant in pesticide and herbicide formulations to improve adhesion and slow release.
• Industrial Dispersions: Aids in the dispersion of fillers and additives in polymer composites and masterbatches.

Quality Control

Our Poly(1-Vinylpyrrolidone)-Graft-(1-Hexadecene) is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance, including parameters such as graft ratio, molecular weight distribution, residual monomer content, and viscosity. Certificates of Analysis (COA) documenting these results are provided and available upon request. We support compliance with relevant cGMP and ISO 9001 standards for industrial and pharmaceutical applications.

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 material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture absorption, which can affect product performance.
