| Abstract |
Mechanochemical reactions, chemical reactions those are induced by the direct absorption of mechanical energy, are promising methods to break and form chemical bonds. Beyond an alternative to thermo-, photo-, or electrochemical activation methods, mechanical-force-driven chemical synthesis can show unexpected reactivity and selectivity, which conventional approaches cannot achieve. Moreover, the exclusion of solvents reduces a processing cost and minimizes the environmental effects.
While many areas of chemistry have enjoyed the merits of mechanochemistry, it has been unexplored in polymer synthesis. Applying mechanical stress on polymeric materials has been regarded to cause degradation. Recently, we stated to pursue the use of mechanical force for the construction of macromolecules and a mechanochemical polymerization of lactide is developed using ball milling. Mechanical energy from the collisions between the balls and the vessel efficiently promoted an organic-base-catalyzed metal- and solvent-free solid-state polymerization. Also solid-state post-polymerization modification was achieved by means of mechanochemistry as well. The current status of mechanochemical polymer synthesis by our research team will be presented.
