What is Dimethylaminoethyl methacrylate?
Dimethylaminoethyl methacrylate (CAS 2867-47-2), commercially known as DMAEMA, is a reactive amino-functional monomer used in the synthesis of specialty polymers and copolymers.
Where is Dimethylaminoethyl methacrylate used?
- Coatings and adhesives: copolymerized to introduce adhesion-promoting and crosslinkable functionality
- Waterborne and UV-curable systems: enhance durability
- Textile and leather: fixatives and softening agents, where cationic charge improves fiber affinity
- Paper manufacturing: wet-strength resins and retention aid formulations
- Printing and packaging: inkjet coatings and binder systems
- Its tertiary amine group enables pH-responsive behavior and cationic character in finished polymer systems.
Good to know: Typically stabilized with a polymerization inhibitor for safe handling and storage during transit. Inhibitor type and concentration are specified on request.
Commercial specifications
- Purity commonly 98% or higher
- Bulk quantities in drums and IBC containers
