2-oxotetrahydrofuran-3-carbonyl acrylate

Core Application Areas and Functional Value

1. Photoresists and Microelectronic Materials

ArF/KrF photoresist monomers: When compounded with adamantyl acrylate, they can regulate the dissolution rate of the resin in the developer solution. The polarity of the tetrahydrofuran ring helps enhance the adhesion of the photoresist to the silicon wafer substrate, while the ketone carbonyl group can increase the dissolution contrast between exposed and unexposed areas through acid-catalyzed reactions (contrast can reach above 4.0), making it suitable for photoresist formulations in the 90-130 nm process.

Electronic packaging materials: Participating in the modification of epoxy resins as a crosslinking monomer, it can reduce the dielectric constant of the packaging material (ε≈3.2) and improve high-frequency signal transmission efficiency, making it suitable for 5G base station chip packaging.

2. Functional Coatings and Adhesives

High-adhesion coatings: When copolymerized with polyurethane acrylate, the resulting coating exhibits adhesion to metals (such as aluminum, copper) (cross-cut test grade 0) that is significantly superior to ordinary acrylate coatings, and the salt spray resistance (no rust after 500 hours) is improved by 30%, making it suitable for corrosion protection in marine engineering.

UV-curable adhesives: Adding 5-15% OTFA can improve the flexibility of the adhesive layer (elongation at break reaches 150%) while maintaining high shear strength (>15 MPa), used for interlayer bonding in flexible electronic devices.

3. Biomedical Materials

Degradable hydrogels: Copolymerized with polyethylene glycol diacrylate (PEGDA) to construct pH-responsive hydrogels (swelling rate increases by 200% at pH<5), used for targeted drug release systems in tumor microenvironments (weakly acidic).

Tissue engineering scaffolds: Porous scaffolds are formed through polymerization of double bonds, and the hydrophilicity of the tetrahydrofuran ring can promote cell adhesion (cell survival rate >90%), making it suitable for cartilage tissue repair.
