Poly( 1-caprolactone) -poly(ethylene glycol) -poly( 1-caprolactone) triblock copolymers (PECL) covering a wide range of poly(ethylene glycol) (PEG) lengths were synthesized with alkali metal alkoxide derivatives of poly(ethylene glycol). The effects of various factors, such as amount of the initiato

## Abstract Biodegradable copolymers were prepared by ring‐opening polymerization of sequentially added __ε__‐caprolactone and DL‐lactide in the presence of ethylene glycol or poly(ethylene glycol), using zinc metal as catalyst. Polymerization was performed in bulk and yielded block copolymers with
## 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
