## Abstract Poly(Lβlactide)βpoly(ethylene glycol) multiblock copolymers with predetermined block lengths were synthesized by polycondensation of PLA diols and PEG diacids. The reaction was carried out under mild conditions, using dicyclohexylcarbodiimide as the coupling agent and dimethylaminopyrid
## Abstract **Summary:** Ringβopening polymerization of D,Lβlactide was carried out in the presence of poly(ethylene glycol), using Zn powder as catalyst. The hydroxylβcapped PLAβPEGβPLA triblock copolymers were coupled with adipoyl chloride at different molar ratios under mild conditions. __N__βDi
