Functional Monomers

N,N-Dimethylaminoethyl Methacrylate (DMAEMA)

N,N-Dimethylaminoethyl Methacrylate, commonly known as DMAEMA (CAS 2867-47-2), is a versatile and high-purity functional monomer belonging to the amino-methacrylate family. It is characterized by the presence of a tertiary amine group and a polymerizable methacrylate moiety, making it an essential building block for advanced specialty polymers. In the global chemical market, DMAEMA serves as a critical intermediate for synthesizing cationic polymers through direct polymerization or subsequent quaternization reactions. Its dual functionality allows for the introduction of both hydrophilic and reactive sites into polymer backbones, enhancing properties like adhesion, solubility, and electrostatic interaction. As a clear, low-viscosity liquid, DMAEMA is prized for its excellent reactivity in free-radical polymerization processes. It plays a pivotal role in diverse sectors, ranging from water treatment and coatings to personal care and pharmaceuticals, where it facilitates the creation of high-performance flocculants, dispersants, and conditioning agents.
