A series of novel triblock copolymers, consisting of a poly(ethylene glycol) center block joined by two blocks of random L-lactide/glycolide copolymers, are synthesized and their characteristics (spectral, thermal, and mechanical) determined. Polymer compositions and structures are assessed via 1 H-

## Abstract Poly(L‐lactide)‐poly(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

Copolymers with a PPG center block and two arms of random glycolide/ lactide copolymers have been synthesized and characterized. Compared to random glycolide/lactide copolymers, these new polymers have high toughness and low elastic modulus. 1 H-NMR spectral lines of glycolide CH 2 protons of the co
