| Outline of Final Research Achievements |
Unprecedented chain-growth polymerizations based on catalytic cycloaddition reactions were developed. Polymerizations of diyne-alkyne AB monomers by catalysis in the presence of ClCl2/dipimp/Zn underwent in a chain-growth fashion to give polymers with narrow polydispersity. By control the reactivity of monomers, one-shot spontaneous block, random, or gradient polymerizations of two different monomers were realized. The method is also applicable to prepare conjugated polymers. The polymerization reaction proceeds through a catalyst-transfer mechanism, in which selection of a ligand for the catalyst complex is important. In addition, alkyne/nitrile [2+2+2] cycloaddition polymerization and diyne/ene [4+2] cycloaddition polymerization were investigated. These polymerization proceeded smoothly to afford the corresponding linear polymers but with wider polydispersity.
