## 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

## Abstract The kinetics and controllability of the Ti[OCH~2~CCl~3~]~4~‐initiated atom transfer radical polymerization (ATRP) of __n__‐butyl acrylate were investigated. Then, with Ti[OCH~2~CCl~3~]~4~ as the initiator, poly(ϵ‐caprolactone)‐__block__‐poly(__n__‐butyl acrylate) (PCL‐__b__‐PBA) copolym
