All polymerizations are classified into two mechanisms, step-growth polymerization and chain-growth polymerization. With decades’ development of controlled living polymerization, it is a general consensus that chain-growth is better to obtain polymers with defined molecular weight, structure, architecture and narrow distribution. Our newly developed chain-growth CuAAC polymerization only suitable for AB2 type monomers. This poster presents our new progress on the chain-growth CuAAC polymerization of AB type monomers by applying active cores in the polymerization to construct star polymers with well-defined molecular weight and polydispersity. By using this method, acid-degradable hyperstar polymers with molecular weight Mn = 2.31×105 and polydispersity Mw/Mn = 1.04 was achieved and further degraded to linear polymer with molecular weight Mn =5.1×103 and polydispersity Mw/Mn = 1.64.
