The synthesis of low-molecular-weight (M V w (GPC) Γ΅ 72000 g mol) lactic- acid-based telechelic prepolymers by condensation polymerization of L-lactic acid was investigated. All polymerizations were carried out in the melt, using tin(II)octoate as catalyst, different diols, and different polymerizat
