The polymerization of D,L-lactide in the presence of zinc metal was investigated for low values of the monomer/catalyst ratio in order to allow endgroup characterization of the growing chains by high resolution 360 MHz 1H NMR. The results showed that the polymerization was moisture sensitive and tha

Lithium chloride was found to be an effective and biocompatible catalyst for the ring-opening polymerization of lactide in the presence of hydroxyl-containing compounds. Ethylene glycol (EG) and methyl ␣-D-glucopyranoside (MGlc) were used as multifunctional initiators. The polymerization was carried
