## Abstract A novel block copolymer, poly(ε‐caprolactone)‐__b__‐poly(4‐vinyl pyridine), was synthesized with a bifunctional initiator strategy. Poly(ε‐caprolactone) prepolymer with a 2,2,6,6‐tetramethylpiperidinyloxy (TEMPO) end group (PCL~T~) was first obtained by coordination polymerization, whic
