α-Methacryloxy-γ-butyrolactone（Cat No.:M039089）is a bifunctional monomer that combines a methacrylate group with a γ-butyrolactone ring. This unique structure allows it to undergo free radical polymerization while retaining a reactive lactone moiety, making it valuable in advanced polymer design. It serves as a versatile building block for synthesizing functionalized polymers, hydrogels, and bioresorbable materials. The lactone ring can be further modified or hydrolyzed, enabling post-polymerization functionalization. Due to its biocompatibility and degradability, α-methacryloxy-γ-butyrolactone is also studied for biomedical applications such as drug delivery, tissue engineering, and environmentally friendly coatings.
