Description

(Dimethylaminomethyl)Styrene is a versatile, reactive monomer featuring both a styrenic double bond and a tertiary amine functional group. This bifunctional nature makes it a critical building block for synthesizing specialty polymers with tailored properties, such as enhanced adhesion, cationic charge, or chemical reactivity. It is particularly valuable for manufacturers in the polymer, coatings, and advanced materials sectors seeking to develop high-performance resins and functionalized materials.

Application

• Cationic Polymer Synthesis: Serves as a key monomer for producing polymers with permanent cationic charge, useful in flocculants, retention aids, and water treatment chemicals.
• Advanced Coating Resins: Incorporated into acrylic and styrenic copolymer systems to improve adhesion to difficult substrates, corrosion resistance, and cross-linking density.
• Ion-Exchange Resins & Chelating Polymers: Used as a precursor for functional resins that selectively bind metal ions or specific anions in purification and separation processes.
• Adhesive & Sealant Formulations: Enhances the bonding strength and chemical resistance of structural adhesives and specialty sealants.
• Photoresist & Electronic Materials: Acts as a functional monomer in photopolymerizable compositions for microelectronics and printed circuit boards.
• Pharmaceutical Intermediates: Employed in the synthesis of complex organic molecules and drug candidates requiring the (dimethylaminomethyl)styrene moiety.
• Surface Modification Agents: Used to graft functional groups onto polymer or inorganic surfaces to alter wettability, printability, or biocompatibility.

Quality Control

Our (Dimethylaminomethyl)Styrene is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee supply chain transparency and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 15-25°C (59-77°F). Keep away from strong bases and incompatible materials such as strong oxidizing agents. For long-term storage, consider under an inert atmosphere (e.g., nitrogen) to minimize polymerization risk.
