As conjugate substitution reaction of α-(substituted methyl)acrylates proceed quantitatively under ambient condition, we applied the reaction to termination of stereospecific living anionic polymerization, polycondensation, main chain scission and transformation reactions. For example, bis[α-(chloromethyl)acrylate] underwent polycondensation with dicarboxylic acid. The obtained poly(ester ester) was decomposed via main chain scission by conjugate substitution reaction with thiols, while similar reactions with dithiols and diamines resulted in main chain transformation from polyester to polysulfide. The main chain transformation is new class of polymer modification reaction consisting of main chain scission and re-polycondensation based on conjugate substitution. Since the polymer chemistry of conjugate substitution reaction can be performed in air, water and solid state at room temperature, we expect the application to self-healing materials, renewable polymers and adhesions. |
