Reversible addition-fragmentation chain transfer (RAFT) radical polymerisation enables to synthesise well-defined homopolymers and block copolymers based on 2-(acetoacetoxy)ethyl methacrylate, which are capable to strongly coordinate to metals and metal ions.

Precisely incorporating a wide range of structural and functional multiblocks along a polymer backbone is a significant challenge in polymer chemistry and offers promising opportunities to design highly ordered materials, including controlled polymer folding. Herein, a facile and versatile strategy
