Synthesis of thermoresponsive PNIPAm-b-PVP-b-PNIPAm hydrogels via aqueous RAFT polymerization

A stimuli-responsive BAB triblock copolymer of PNIPAm- b -PVP- b -PNIPAm, which displayed a thermoreversible sol–gel transition, was readily synthesized via redox-initiated aqueous RAFT mediated polymerization, under mild conditions.
