Description

Polyoxy(1-Oxo-1,6-Hexanediyl), .Alpha.-2-(2-Methyl-1-Oxo-2-Propenyl)Oxyethyl-.Omega.-Hydroxy- is a specialized functional polymer, specifically a methacrylate-terminated polycaprolactone macromonomer. This compound matters for its unique bifunctional nature, combining a polymerizable methacrylate end-group with a biodegradable polycaprolactone chain and a terminal hydroxyl group, enabling precise chemical modifications and controlled material properties. It is primarily needed by R&D chemists and formulators in the advanced polymer, biomedical, and specialty coatings industries for creating tailored, high-performance materials.

Application

• Biomedical Polymers: As a key macromonomer for synthesizing biodegradable hydrogels, drug delivery systems, and tissue engineering scaffolds.
• Specialty Coatings & Adhesives: Used to formulate advanced, cross-linkable coatings with enhanced toughness, flexibility, and controlled degradation profiles.
• Dental & Orthopedic Materials: Serves as a reactive prepolymer in the development of biocompatible resins and bone cements.
• Controlled Release Systems: Incorporated into polymer networks to regulate the release rate of active pharmaceutical ingredients (APIs) or agrochemicals.
• Polymer Modification: Employed to graft functional polycaprolactone segments onto other polymer backbones, improving compatibility and biodegradability.
• 3D Printing Resins: Acts as a functional oligomer in photopolymerizable resin formulations for stereolithography (SLA) or digital light processing (DLP), offering tunable mechanical properties.
