Abstract: Polymeric fluorescent brighteners (PFBs) which are polymerized by fluorescent monomer and other monomers can solve poor photostability of traditional FBs.Classification of the PFBs is briefly introduced.The synthesis, structure, properties and application of stilbene, naphthalimide and pyrene FBs are discussed. The basic structure of chromogen in PFBs remains the same,so PFBs have fluorescent properties of traditional FBs.Covalent bonds between chromogen and macromolecule chains enhance their photochemical stability，increase their whitening performance and fluorescence quantum yield. PFBs can be used not only for textile, polymeric materials and detergents，but also for high technology fields，such as liquid crystal displays，fluorescent probes, etc.Developing environmentally friendly high performance new products, mixing different PFBs and polymerizing more monomers with different chromogens are likely to be new areas of research.
