Applications
1. Specialty Polymers and Coatings
Monomer for polymer synthesis, particularly in UV-curable or thermal-curable resins.
Offers functionality for adhesion, crosslinking, or surface reactivity due to its β-ketoester moiety.
Improves chemical and thermal resistance in coatings and adhesives.
2. Dental and Biomedical Materials
Used in dental resins, composites, or adhesives due to its polymerizable methacrylate group.
β-Ketoesters are known for potential biodegradable polymer networks.
3. Functional Resins
Reactive sites can be exploited in copolymer formulations to create tailored surface properties (e.g., hydrophobic/hydrophilic balance, chelation potential).
May be used in inks, sealants, and elastomers with special property requirements.
4. Synthesis Intermediate
Acts as a functional building block in organic synthesis or macromolecular design, especially where ketone or ester groups are strategically useful.
Benefits
Dual-reactivity: Can undergo both radical polymerization (via methacrylate) and nucleophilic reactions (via ketoester).
Versatility: Can be incorporated into a wide variety of polymer matrices.
Adhesion Promotion: Ester and ketone functionalities improve bonding to diverse substrates.
Thermal and UV Stability: Methacrylate-derived networks typically offer good environmental resistance.
Summary
3-Oxo-butyric acid 2-(2-methylacryloyloxy)ethyl ester丨CAS 21282-97-3 is a specialty monomer that offers a combination of polymerizable methacrylate and reactive ketoester functionality. It is valuable in producing high-performance coatings, adhesives, and dental materials due to its reactivity, stability, and surface modification potential.
