Caprolactone 2-(methacryloyloxy)ethyl ester
Caprolactone 2-(methacryloyloxy)ethyl ester (CAS 85099-10-1), with the linear formula HO(CH2)5CO2CH2CH2O2CC(CH3)=CH2 and a molecular weight of 244.28 g/mol, is an acrylic monomer. It finds utility in materials science and polymer science for the synthesis of specialised polymers and coatings, offering unique properties due to its dual functional groups.
Polymer Synthesis
This monomer can be incorporated into polymer chains via its methacrylate group, enabling the creation of polymers with pendant caprolactone rings. These can be further modified or used to tailor polymer properties such as flexibility and hydrophilicity.
Coatings and Adhesives
Its reactive methacrylate functionality allows for UV or radical curing, making it suitable for formulating advanced coatings and adhesives. The caprolactone moiety can impart enhanced flexibility and impact resistance to the final product.
Materials Science Research
As a versatile building block, it is used in research for developing novel materials with specific thermal or mechanical characteristics. The hydroxyl group offers a site for post-polymerization modification or crosslinking.
