A Simple and Rapid Preparation of Poly(Glycolide) (PGA) Oligomers Catalyzed by Decamolybdate Anion in the Presence of Aliphatic Alcohols

Poly(glycolide) (PGA) oligomers were obtained by ring-opening polymerization (ROP) of glycolide (GA) catalyzed by ammonium decamolybdate (NH4)8[Mo10O34] and using aliphatic primary alcohols as initiators/chain transfer agents (HO‒CH2‒[CH2‒CH2]m‒CH3, where m = 1, 2, 4, 5, 6, 7, 8, 9, and 10). High yield (85–95%) and short reaction time (15 min) were observed. The characterization of PGA oligomers was determined by 1H and 13C NMR, FT-IR, and DSC.
