Abstract
The copolymerization of glycolide-lactide is studied by using stannous octoate as an initiator, The contents of two monomer units in copolym ers were determined by H-1 NMR spectra. The reactivity ratios of monom ers were evaluated by Kelen-Tudos method and least-square-calculation. The monomer reactivity ratios of glycolide and lactide are r(1) = 3.4 0 and r(2) = 0.22 respectively.
