2-Aminoethyl Methacrylate Hydrochloride (AEMA HCl) is a hydrophilic, amine-functional methacrylate monomer used to introduce primary amine functionality into polymers and copolymers. Its methacrylate group supports polymerization with compatible acrylic and methacrylic monomers.
Synonyms: AEMA; 2-Aminoethyl 2-Methylprop-2-enoate Hydrochloride; Methacrylic Acid 2-Aminoethyl Ester Hydrochloride.
The primary amine functionality provides a reactive site for subsequent coupling, crosslinking, or surface-modification reactions. AEMA HCl may be used to prepare functional polymers where hydrophilic or amine-reactive properties are required.
Product 21002 has a minimum chemical purity of 95%, is supplied without an inhibitor, and is soluble in water. Polymerization and functionalization conditions should be established for the selected monomers, initiator system, solvent, and intended material properties.

Applications
Functional Polymer Synthesis
AEMA HCl may be copolymerized with compatible acrylic and methacrylic monomers to introduce primary amine functionality into polymer systems.
Post-Polymerization Functionalization
The primary amine groups incorporated into a polymer can provide reactive sites for subsequent coupling, derivatization, or crosslinking reactions.
Hydrogel & Hydrophilic Polymer Research
May be evaluated in hydrogel and hydrophilic polymer formulations where amine functionality or additional sites for chemical modification are required.
Coatings & Surface Modification
AEMA HCl may be used in research involving functional coatings and surfaces designed for subsequent reaction with amine-compatible reagents.
Compatibility & Polymerization Considerations
- Compatible with appropriately selected acrylic and methacrylic polymerization systems
- Primary amine functionality may influence polymer charge, solubility, and interfacial behavior
- Performance depends on monomer concentration, comonomers, initiator system, solvent, pH, and temperature
- Because the product is uninhibited, polymerization conditions and storage practices require careful control
The appropriate AEMA HCl concentration and processing conditions depend on the intended polymer structure and required performance. Compatibility should be evaluated with all monomers, initiators, crosslinkers, solvents, and other formulation components.
Application Tips
- Use controlled, small-scale trials to establish suitable polymerization conditions
- Dissolve and mix thoroughly to support uniform incorporation into the reaction system
- Account for the primary amine group when selecting reaction pH and coupling chemistry
- Confirm monomer conversion and functional-group incorporation using appropriate analytical methods
Handling & Storage
- Store at 4°C
- Keep the container securely closed when not in use
- Handle with protective gloves and chemical goggles in a fume hood
- Protect the uninhibited monomer from unsuitable heat and polymerization conditions
