## Abstract Hexaarmed star‐shaped hydroxyl‐terminated poly(ε‐caprolactone) (PCL) was successfully synthesized via the ring‐opening polymerization of ε‐caprolactone (CL) with hexakis[__p__‐(hydroxymethyl)phenoxy]cyclotriphosphazene initiator and stannous octoate catalyst in bulk. The star‐shaped PCL
Poly(D,L-lactide) -poly(1-caprolactone) -poly(ethylene glycol) -poly(1-caprolactone) -poly (D,L-lactide) block copolymer (PLA-PCL-PEG-PCL-PLA) was prepared by copolymerization of 1-caprolactone (1-CL) and D,L-lactide (D,L-LA) initiated by potassium poly(ethylene glycol)ate in THF at 25ЊC. The copoly
The reductive coupling of aromatic monocarbonyl compounds in the presence of SmI 2 results in the formation of Samarium(III) dialkoxides. These Sm(III) dialkoxides have been utilized as initiators for ring opening polymerization (ROP) of lactones and lactides. The reductive coupling of aromatic dica
