is a radical of formula —X; and X is a functionalised radical. The invention relates to the method for preparing same and the uses thereof.
The amphiphilicA2B star‐shaped copolymers of polystyrene‐b‐[poly(ethyleneoxide)]2 (PS‐b‐PEO2) were synthesized via the combination of atomtransfernitroxideradicalcoupling (ATNRC) with ring‐opening polymerization (ROP) and atomtransferradical polymerization (ATRP) mechanisms. First, a novel V‐shaped 2,2,6,6‐tetramethylpiperidine‐1‐oxyl‐PEO2 (TEMPO‐PEO2) with a TEMPO group at middle chain was
