(3R,3aS,6R,7R,8aS)-3,6,8,8-Tetramethyloctahydro-1H-3a,7-methanoazulen-6-yl acrylate
(3R,3aS,6R,7R,8aS)-3,6,8,8-Tetramethyloctahydro-1H-3a,7-methanoazulen-6-yl acrylate, commonly known as Cedryl acrylate, is a specialized monofunctional monomer derived from the tricyclic sesquiterpene alcohol, cedrol. This compound features a bulky, rigid cedrane skeleton coupled with a reactive acrylate moiety. Its unique chemical architecture imparts specific physical properties, such as low shrinkage during polymerization and a high refractive index, making it a valuable building block in the synthesis of high-performance polymers and specialty resins.
In industrial and research settings, this material is valued for its ability to modify the mechanical and thermal characteristics of copolymer systems. Due to its hydrophobic nature and sterically hindered structure, it enhances the water resistance and glass transition temperature of resulting materials. Handling requires standard precautions for acrylate monomers, including protection from light and heat to prevent premature polymerization, and it is typically stabilized with inhibitors to ensure shelf-life stability during transport and storage.
• Used extensively as a specialty monomer in the formulation of UV-curable and electron-beam (EB) curable coatings. The inclusion of the bulky cedryl group helps to reduce volume shrinkage during the curing process, which improves adhesion to various substrates and minimizes internal stress within the coating film. This makes it particularly suitable for precision optical coatings and protective layers where dimensional stability is critical.
• Serves as a high-performance reactive diluent in adhesive systems and structural resins. Its unique tricyclic structure contributes to an increase in the glass transition temperature (Tg) of the final polymer matrix, enhancing the thermal stability and mechanical rigidity of the bonded assembly. Additionally, its inherent hydrophobicity provides superior moisture resistance, protecting the integrity of the polymer network in humid or outdoor environments.
• Utilized in the development of advanced optical materials and electronic components. The high refractive index and low birefringence associated with the cedrane backbone allow for the creation of specialized lenses, light-guide plates, and encapsulation materials for optoelectronic devices. Its ability to copolymerize with a wide range of other acrylic monomers enables fine-tuning of the optical and physical properties of the resulting resin.
