Post-polymerization modification/functionalization has been an important endeavor in polymer chemistry as well as materials science ever since the work of Staudinger. However, it has become much more relevant in the last two decades with the advent of click chemistry. Even though click reactions are, by definition, high yielding and efficient, clicking functionality onto organic polymers is still hindered by the need for organic solvents as reaction media (rendering these processes less “green”). This poster describes our current efforts geared toward the use of mechanochemistry as a tool for performing post-polymerization (i) thio-bromo click and (ii) copper-catalyzed azide/alkyne cycloaddition modifications under solvent-free conditions on polynorbornene derivatives containing α-bromo ester and azido groups, respectively.
