甲基丙烯酸烯丙酯（AMA）

Allyl Methacrylate (AMA), identified by CAS Number 96-05-9, is a sophisticated bifunctional monomer that serves as a cornerstone in modern polymer chemistry. Characterized by its unique molecular structure containing both a highly reactive methacrylate group and a secondary allyl group, AMA offers differential reactivity that is highly prized by resin formulators. The methacrylate moiety typically undergoes rapid free-radical polymerization, while the allyl group provides a latent site for cross-linking, grafting, or functionalization during subsequent curing stages. This dual-action capability makes AMA an essential building block for creating complex polymer architectures with high cross-link density. As a colorless liquid with a distinctive ester odor, it is classified as a specialty ester used to bridge the gap between linear chains and rigid networks. Its market role is critical in high-performance sectors where thermal stability, chemical resistance, and mechanical toughness are non-negotiable requirements for finished products.
