Bisphenol A
CAS Number: 80-05-7
Bisphenol A (BPA) is the difunctional phenolic monomer for standard epoxy resins (DGEBA) and polycarbonate (PC) production. BPA reacts with epichlorohydrin to form diglycidyl ether of BPA, the most widely used epoxy resin. In polycarbonate synthesis, BPA undergoes interfacial phosgenation or transesterification with diphenyl carbonate.
