Beschreibung
Zusammenfassung:	The present invention relates to a polyesteramide resin, a manufacturing method thereof, and a biaxially stretched film comprising the same. Specifically, the embodiments of the present invention provide the polyesteramide resin into which a diamine moiety is introduced in addition to a diacid moiety and a diol moiety, the manufacturing method thereof, and the biaxially stretched film comprising the same. In the present invention, the polyesteramide resin has improved heat resistance (particularly, thermal properties such as Tg) and film properties (particularly, physical properties such as tensile strength and storage modulus) compared to generally known polyester resins. 본 발명은 폴리에스테르아미드 수지, 이의 제조 방법, 및 이를 포함하는 이축 연신 필름에 관한 것이다. 구체적으로, 본 발명의 구현예들은, 이산 잔기 및 다이올 잔기와 더불어 다이아민 잔기가 도입된 폴리에스테르아미드 수지, 이의 제조 방법, 및 이를 포함하는 이축 연신 필름을 제공한다.
