## Abstract Radical polymerization of styrene and mixtures of styrene and 4‐vinylpyridine was performed in the presence of 2,2,6,6‐tetramethylpiperidine‐__N__‐oxyl (TEMPO) producing polymers with controlled molecular weights and molecular weight distributions. The living nature of these polymers wa
## Abstract Summary: Well‐defined AB~2~ 3‐ and AB~4~ 5‐miktoarm star copolymers were prepared by combination of ring‐opening polymerization (ROP) and nitroxide‐mediated radical polymerization (NMRP) using dendritic tri‐ and penta‐functional initiators. Initially, two kinds of dendritic initiators h
## 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
Synthesis of poly(styrene-b-tetrahydrofuran (THF)-b-styrene) triblock copolymers was performed by transformation from living cationic into living radical polymerization, using 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (4-hydroxy-TEMPO) as a transforming agent.

## 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
