## Abstract Poly(ϵ‐caprolactone) (PCL) and its block copolymers with poly(ethylene glycol) (PEG) were prepared by ring‐opening polymerization of ϵ‐caprolactone in the presence of ethylene glycol or PEG, using zinc metal as catalyst. The resulting polymers were characterized by various analytical te

## Abstract Model poly[ethylene‐__block__‐(L,L‐lactide)] (PE‐__block__‐PLA) block copolymers were successfully synthesized by combining metallocene catalyzed ethylene oligomerization with ring‐opening polymerization (ROP) of L,L‐lactide (LA). Hydroxy‐terminated polyethylene (PE‐OH) macroinitiator w
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
