A completely metal free route to obtain poly(acrylicacid-b-e-caprolactone) copolymers P(AA-b-CL) by anone-pot method through simultaneous ReversibleAddition-Fragmentation Chain Transfer (RAFT) and RingOpening Polymerization (ROP) process is reported1.The strategy employs a dual initiator that acts as chaintransfer agent (CTA) in the acrylic acid (AA) RAFTpolymerization process, and as co-initiator ofe-caprolactone (e-CL) ring-opening polymerization(ROP).
