Abstract
This focused review provides an overview of our recent work and related research regarding the precise anionic ring-opening polymerization (AROP) of substituted epoxides, including alkylene oxides, glycidyl ethers, and glycidyl amines, using t-Bu-P4 as the phosphazene base catalyst to produce functional polyethers, such as homopolymers, block copolymers (BCPs), and topologically unique polymers. First, the fundamental aspects and applicable monomer scope of t-Bu-P4-catalyzed AROP are discussed. Subsequently, the applications of well-defined polyethers prepared via t-Bu-P4-catalyzed AROP to develop functional materials, such as thermoresponsive polymers and Li+ conducting polymers, are discussed. Finally, the utility of t-Bu-P4-catalyzed AROP in the precise synthesis of star-shaped, cyclic, and multicyclic polymers is presented. Overall, we intend to illustrate the exploitable utility of the present polymerization system for fundamental and advanced polymer research.
