1-Ethylcyclopentyl methacrylate（Cat No.:L037763）is a methacrylate ester monomer featuring a 1-ethylcyclopentyl group attached to the methacrylate backbone. This compound is used in polymer chemistry to create specialty acrylic resins with enhanced mechanical properties, hydrophobicity, and flexibility. The bulky, cyclic substituent imparts steric hindrance, which can influence polymer packing, glass transition temperature, and optical clarity. It is particularly valuable in coatings, adhesives, and medical materials where customized surface or thermal characteristics are required. The methacrylate group allows for radical polymerization, making it compatible with a wide range of copolymer systems.
