Dimethylaminoethyl Methacrylate
CAS Number: 2867-47-2
Dimethylaminoethyl methacrylate (DMAEMA) is a tertiary amine-functional methacrylic monomer used to produce cationic and pH-responsive polymers. Quaternized or protonated DMAEMA copolymers are widely used in hair care polymers, cationic flocculants, antimicrobial coatings, and gene delivery carriers.
