## 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
## Abstract Biodegradable copolymers were prepared by ring‐opening polymerization of sequentially added __ε__‐caprolactone and DL‐lactide in the presence of ethylene glycol or poly(ethylene glycol), using zinc metal as catalyst. Polymerization was performed in bulk and yielded block copolymers with
