Description

2H-Azepin-2-One, Hexahydro-, Polymer With .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl) is a specialized polymeric compound, also known as a caprolactam-polyethylene glycol block copolymer. This material is engineered to combine the structural properties of polyamide precursors with the hydrophilic, solubilizing, and plasticizing characteristics of polyether segments. It serves as a crucial performance additive and intermediate in advanced material science, enabling the modification of polymer properties and the creation of novel functional materials. Key industries that utilize this polymer include pharmaceuticals, specialty coatings, adhesives, and high-performance resin formulations.

Application

• Pharmaceutical Excipient: Used as a solubilizer, bioavailability enhancer, or controlled-release matrix former in solid dosage forms and drug delivery systems.
• Polymer Modification: Acts as a compatibilizer, plasticizer, or toughening agent in nylon (polyamide) and other engineering plastic blends to improve impact strength and processing.
• Specialty Coatings & Inks: Imparts flexibility, adhesion, and moisture resistance in high-performance coating, ink, and film applications.
• Adhesive & Sealant Formulations: Serves as a key component to enhance bonding strength, elasticity, and environmental durability.
• Fiber & Textile Processing: Used as a spin finish additive or processing aid to improve fiber lubrication, antistatic properties, and dye uptake.
• Personal Care Products: Functions as a film-forming agent, viscosity modifier, or encapsulating material in advanced cosmetic and skincare formulations.

Quality Control

Our production of this block copolymer adheres to strict quality management systems. Each batch is characterized using advanced analytical techniques to ensure consistent molecular weight distribution, block ratio, and functional performance. Certificates of Analysis (COA) are provided, detailing key parameters such as composition, viscosity, and residual monomer content. We support compliance with relevant frameworks for industrial and pharmaceutical intermediates. Specifications can be developed in alignment with customer requirements for specific applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This polymer may be hygroscopic (moisture-sensitive); prolonged exposure to high humidity should be avoided to prevent clumping or property changes. Keep away from strong oxidizing agents.
