Method for preparing biodegradable polyester copolymer and polyester copolymer prepared thereby |
| abstract |
The present invention provides a method of preparing a polyester-based polymer and a polyester-based polymer prepared by the method. The method of preparing the polyester-based polymer includes a prepolymerization step of polymerizing a dicarboxylic acid compound (A), a diol compound (B), and a carbodiimide compound (C) at 160-220 °C to produce a prepolymer; and a condensation polymerization step of performing a condensation polymerization of the prepolymer at 200-250 °C, under a vacuum pressure of 0.1 to 2 Torr. |
