Beschreibung
Zusammenfassung:	The present invention relates to a polyester resin including a diester compound and anhydrosugar alcohol, and a method for preparing same. The polyester resin has excellent heat resistance and mechanical properties and also has excellent biodegradability, as specific amounts of diester components including a succinic acid diester compound and diol components including anhydrosugar alcohol are copolymerized. La présente invention concerne une résine de polymère de polyester comprenant un composé diester et un alcool d'anhydrosucre, et son procédé de préparation. La résine de polyester a une excellente résistance thermique et des propriétés mécaniques et a également une excellente biodégradabilité, lorsque des quantités spécifiques de composants diesters comprenant un composé diester d'acide succinique et des composants diol comprenant un alcool d'anhydrosucre sont copolymérisés. 본 발명은 디에스테르 화합물과 무수당 알코올을 포함하는 폴리에스테르 수지 및 그 제조 방법에 관한 것으로서, 숙신산 디에스테르 화합물을 포함하는 디에스테르 성분과 무수당 알코올을 포함하는 디올 성분을 특정 함량으로 공중합함으로써, 내열성과 기계적 물성이 우수할 뿐만 아니라 생분해성도 우수한 폴리에스테르 수지 및 그 제조 방법에 관한 것이다.
