PROBLEM TO BE SOLVED: To provide a method for efficiently synthesizing a biodegradable copolymer in a short time. SOLUTION: One or more kinds of biodegradable monomers selected from the group consisting of a glycolide, L-lactide, D, L-lactide,β-propionelactone,γ-butyrolactone,δ-valerolactone,β-methyl-δ-valerolactone,ε-caprolactone, D, L-mavalonolactone, trimethylene carbonate, 1-methyltrimethylene carbonate, 2,2-dimethyltrimethylene carbonate, tetramethylene carbonate, 1,5-dioxepan-2-one, morpholin-2,5-dione, 3,6-dimethylmorpholin-2,5-dione, (R)-or-(S)-3-methyl-4-oxa-6-hexanolide (MOHEL), ethylene oxide and 5-methyl-5-benzyloxy-1,3-dioxan-2-one are subjected to a ring-opening polymerization by a microwave irradiation.
