Lanthanide tris(2,4,6-tri-tert-butylphenolate)s are highly active initiators for ring-opening polymerization of ε-caprolactone to give polycaprolactone with number average molecular weight as high as 8.3 × 10 4 at 20 • C in 20 min in toluene. The effects of solvent, rare earth element, monomer/initi

Time dependence of the yields in c-acryloyloxyethyl-c-butyrolactone and poly(c-acryloyloxy-e-caprolactone) in toluene at 0 8C. Conditions: [ACL] 0 = 1 m, [ACL] 0 /[Al(O i Pr) 3 ] 0 = 50 (ACL: c-acryloyloxy-e-caprolactone). Scheme 1.
## 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
