Poly(ethylene glycol)-poly(L-lactide) diblock and triblock copolymers were prepared by ring-opening polymerization of L-lactide with poly(ethylene glycol) methyl ether or with poly(ethylene glycol) in the presence of stannous octoate. Molecular weight, thermal properties, and crystalline structure o

## SYNOPSIS Blends of poly(L-lactide) (PLLA) and poly(e-caprolactone) (PCL) were prepared in a corotating twin screw miniextruder (40 rpm, 200"). It was attempted to prepare multiblock copolymers by allowing a controlled number of transesterification reactions. Various catalysts (n-Bu,SnOMe, Sn(Oc
## Abstract A biodegradable block copolymer, poly‐D,L‐lactide (PLA)‐__co__‐poly(ethylene glycol) (PEG), was prepared by the ring‐opening polymerization of lactide with stannous caprylate [Sn(Oct~2~)] as a catalyst; then, the PLA–PEG copolymer was made into nanoparticles by nanoprecipitation under d
## Abstract Core–shell type nanoparticles of poly(L‐lactide)/poly(ethylene glycol) (LE) diblock copolymer were prepared by a dialysis technique. Their size was confirmed as 40–70 nm using photon correlation spectroscopy. The ^1^H‐NMR analysis confirmed the formation of core–shell type nanoparticles
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
