Development of Investigation on the Synthesis of Hyperbranched Polymers

Hyperbranched polymers are one type of dendritic macromolecules which can be synthesized by one-step polymerization process.Because of the special structures and properties,as well as the possibility of large-scale production,twenty years of research on hyperbranched polymers have made it become one of the most important kinds of polymer materials rapidly,which have broad application potentials.This paper reviews the main synthetic methods of hyperbranched polymers and the developing history from the aspects of monomers,which involving ABx monomers,AB* monomers,A_2 B_3 monomers,and the latent AB_x monomers(including ring-opening polymerization and couple-monomer methodology),etc.The excellence and the limiting of each method are also introduced.
