Abstract: The copolymerization of glycolide-lactide is studied by using stannous octoate as an initiator.The contents of two monomer units in copolymers were determined by 1HNMRspectra.The reactivity ratios of monomers were evaluated by Kelen Tudos method and leastsquare-calculation.The monomer reactivity ratlos of glycolide and lactlde are r1=3.4O and r2=O.22 respectively.

Key words: Glycolide, Lactide, Copolymerization, Reactivlty ratio
