反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Polymerization and post-treatment were performed in the same manner as in Polymer Preparation Example 1 except that a mixture of 200 g of glycolide and 10 g of ethylene oxalate (1,4-dioxane-2,3-dione) was used in place of 210 g of glycolide, thereby obtaining a glycolic acid-ethylene oxalate copolymer [Polymer (P-2)]. The same process was conducted repeatedly to prepare a necessary amount of Polymer (P-2). Polymerization
