Facile synthesis of temperature-sensitive ABA triblock copolymers by dispersion RAFT polymerization

The dispersion RAFT polymerization was applied for the first time to synthesize the well-defined ABA triblock copolymer core–shell nanoparticles of temperature-sensitive poly(N-isopropylacrylamide-co-acrylic acid)-block-poly(n-butyl acrylate)-block-poly(N-isopropylacrylamide-co-acrylic acid) and poly(n-butyl acrylate-co-N-isopropylacrylamide)-blockpoly(n-butyl acrylate)-block-poly(n-butyl acrylate-co-N-isopropylacrylamide).
