Polymerization of 1-caprolactone had been investigated with cyclopentadienyl sodium as an initiator. The effects of reaction time, temperature, and concentration of the initiator on the yield and molecular weight of the polymer were discussed. It was shown that the high molecular weight of poly(1-ca

A novel 5'-deoxy-5-fluorouridine-poly(epsilon-caprolactone) (5'-DFUR-PCL) polymer was synthesized from the antitumor agent doxifluridine (5'-DFUR) by the ring-opening polymerization of epsilon-caprolactone (epsilon-CL) using Sn(II) 2-ethylhexanoate (Sn(Oct)2) as the catalyst. The structure and molec
## Abstract Summary: The synthesis of core‐shell particles with a poly(__ε__‐caprolactone) (PCL) shell and magnetite (Fe~3~O~4~) contents of between 10 wt.‐% and 41 wt.‐% proceeds by surface‐initiated ring‐opening polymerization of __ε__‐caprolactone to give surface‐immobilized oligomers with $\ove
