3,3-DimethylacrylicAcidMethylEster CAS:924-50-5

3,3-Dimethylacrylic acid methyl ester finds application as a monomer for producing specialized poly(alkyl methacrylate) polymers. The bulky tert-butyl substituents enable synthesis of amorphous, glassy polymers with high glass transition temperatures suitable for coatings on optical fibers, resist sheets and photoresists. It polymerizes via free radical mechanisms to form hydrophobic, UV-resistant coatings. As the substituents hinder chain transfer and termination, controlled polymerization gives precise polymers. It is also used in dental materials and biomedicine to prepare polymers that are non-cytotoxic and durable under physiological conditions. Further, it assists synthesis of stimuli-responsive gels for targeted drug delivery and tissue engineering matrices. Research finds this monomer valuable for developing non-fouling coatings, optoelectronics, and holographic data storage due to its tunable photopolymerization properties.
