Description

Poly(Acryloyl Chloride) is a highly reactive bifunctional monomer featuring both a polymerizable vinyl group and an acid chloride moiety. This dual functionality makes it a critical building block for synthesizing advanced polymers with tailored properties. It is essential for manufacturers in the specialty chemical, pharmaceutical, and advanced materials sectors seeking to introduce reactive pendant groups or cross-linkable sites into polymer chains. The compound is commercially available under CAS No. 25189-84-8.

Application

• Synthesis of Reactive Polymers: Used to prepare poly(acrylic acid) derivatives, polyacrylamides, and other functional polymers via post-polymerization modification.
• Production of Hydrogels & Smart Materials: Serves as a cross-linking agent or functional monomer for creating pH-responsive or temperature-sensitive hydrogels for biomedical and sensor applications.
• Surface Modification & Coatings: Employed to graft polymer brushes or functional layers onto surfaces (e.g., silica, metals) to alter wettability, adhesion, or biocompatibility.
• Pharmaceutical Intermediates: Acts as a key reagent for coupling drug molecules to polymeric carriers or for synthesizing prodrugs and controlled-release systems.
• Chromatography Media: Functionalizes support materials (e.g., agarose, silica) to create affinity chromatography resins for protein purification.
• Adhesive & Sealant Formulations: Incorporated to enhance the chemical resistance, adhesion, or curing characteristics of high-performance adhesives.
• Optical & Electronic Materials: Used in the synthesis of polymers for photoresists, organic light-emitting diodes (OLEDs), and other optoelectronic devices.

Quality Control

Our Poly(Acryloyl Chloride) is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, functionality, and purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for the specific grade. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain reactivity. Keep away from strong bases, alcohols, and water.
