2,6-Bis(1,1-dimethylethyl)-4-(phenylmethylene)-2,5-cyclohexadien-1-one (CAS: 7078-98-0) is a highly efficient high-temperature polymerization inhibitor, radical scavenger, and polymer stabilizer. Featuring a conjugated quinone methide architecture, it exhibits superior radical-trapping capabilities at elevated temperatures. It is extensively utilized to prevent premature thermal polymerization during the purification, distillation, storage, and transportation of reactive monomers, including styrene, acrylates, and conjugated dienes. In synthetic rubber processing (such as polybutadiene, EPDM, and high-vinyl rubbers), it effectively prevents cross-linking, gelation, and thermal degradation. Additionally, this compound functions as an advanced antioxidant additive for engineering plastics, industrial lubricants, and high-temperature greases, significantly enhancing thermal-oxidative stability and operational lifespan.
