Description

5',5''-Bis(4-Aminophenyl)-2',2'',4',4'',6',6''-Hexamethyl-[1,1':3',1'':3'',1'''-Quaterphenyl]-4,4'''-Diamine is a high-purity, multifunctional aromatic diamine monomer characterized by its extended, rigid quaterphenyl core structure. This compound matters for its role as a critical building block in the synthesis of advanced polymers, where its multiple amine groups and sterically hindered, planar architecture enable the creation of materials with exceptional thermal stability, mechanical strength, and tailored optical properties. It is primarily needed by R&D chemists and material scientists in the high-performance polymer, liquid crystal, and organic electronics industries for developing next-generation polyimides, epoxy resins, and specialty coatings.

Application

• High-Performance Polyimide Synthesis: Serves as a key diamine monomer for producing polyimide films and resins with superior thermal oxidative stability, low dielectric constant, and high glass transition temperatures, suitable for flexible electronics and aerospace applications.
