A facile and versatile approach for preparing CO2-responsive graft copolymers via a grafting-to strategy that combines controlled radical polymerization with post-polymerization modification has been demonstrated. A well-defined poly(N,N-dimethylacrylamide-co-pentafluorophenyl acrylate) (P(DMA-co-PFPA)) was synthesized by reversible addition fragmentation chain transfer (RAFT) polymerization bearing reactive pentafluorophenyl esters as grafting sites on a hydrophilic backbone. Then, amino end-functionalized poly(2-(diethylamino)ethyl methacrylate) (PDEAEMA) known for its CO2 responsiveness and hydrophobic poly(Me methacrylate) (PMMA) were prepared via atom transfer radical polymerization (ATRP) as side blocks, resp. The post-polymerization modification via active-ester amine chem. resulted in CO2-responsive graft copolymers with either homo-side chains or discrete multi-functional hetero side chains. The grafting-to strategy utilizing active-ester amine chem. appeared to be a facile and efficient method to fabricate graft copolymers. Both prepared CO2-responsive graft copolymers – due to their amphiphilic nature – could self-assemble into vesicles in aqueous solution and displayed CO2-responsive expansion owing to the protonation of tertiary amine groups of PDEAEMA side chains under CO2 stimulation.
