Abstract
A method of preparing a biodegradable polyester resin is provided. The method of preparing a biodegradable polyester resin includes: (a) synthesizing the biodegradable polyester resin having a reheating crystallization initiation temperature (T), a reheating crystallization peak temperature (T), and a reheating crystallization end temperature (T); and (b) crystallizing the biodegradable polyester resin synthesized in step (a) by cooling the resin from a temperature of Tto a temperature of Tand then maintaining the resin at a temperature of Tfor a time of t. Thus, the biodegradable polyester resin with improved solidification rate may be obtained.
