One of the great challenges in the field of polymer synthesis is the construction of well-defined polymer backbones with controlled molecular weights and narrow polydispersities. In this study, we report the controlled synthesis of a condensation polymer, poly(phenylene oxide) containing pendent trifluoromethyl groups, from an AB' type monomer having a reactive A and a latent B' functional group. The monomer did not react with itself under certain polymerization condition. However, in the presence of a reactive B type initiator, the polymerization of the monomer occurred in a chain growth manner, through the selective and consecutive nucleophilic aromatic substitution reactions with the initiator followed by the chain end of a growing polymer, to the poly(phenylene oxide) with controlled molecular weights and narrow polydispersities. Details of the polymerization, structure and properties of the polymer will be presented. |
