Water-soluble macromolecular chain transfer agents (Macro-CTAs) were developed for the microwave-assisted precipitation polymerization of N-isopropylacrylamide. Two types of Macro-CTAs, amphiphilic (Macro-CTA1) and hydrophilic (Macro-CTA2), were investigated regarding their activity for the facile formation of nanoparticles and double hydrophilic block copolymers by RAFT processes. While both M...
