In this contribution we report the use of the RAFT‐technique for the preparation of three types of responsive polymeric materials with a high potential of application in the biomedical field: 1.‐Diblock copolymers with reversible self‐assembly capacity as a function of pH based on N,N′ ‐diethylaminoethyl methacrylate (DEAEM) and 2‐methacryloyloxy benzoic acid (MAOB); 2.‐Diblock copolymers with reversible self‐assembly capacity as a function of temperature, based N ‐isopropylacrylamide (NIPAAm) and n‐hexyl acrylate (HA); and 3.‐Polymeric stars with random number of arms consisting either in NIPAAm‐arms or copolymeric NIPAAm‐arms and hydrophobic core.
