Beschreibung
Zusammenfassung:	The present invention relates to: a polyester resin mixture comprising a polyester copolymer prepared using a recycled monomer; a method for preparing same; and a polyester film prepared thereby, wherein the polyester resin mixture has excellent extrusion properties (processability), and thus can provide a polyester film having excellent physical properties and/or quality. La présente invention concerne : un mélange de résine de polyester comprenant un copolymère de polyester préparé à l'aide d'un monomère recyclé ; un procédé de préparation de celui-ci ; et un film de polyester préparé par celui-ci, le mélange de résine de polyester ayant d'excellentes propriétés d'extrusion (aptitude au traitement), et pouvant ainsi fournir un film de polyester ayant d'excellentes propriétés physiques et/ou une excellente qualité. 본 발명은 재생 단량체를 이용하여 제조한 폴리에스테르 공중합체를 포함하는 폴리에스테르 수지 혼합물, 이의 제조방법 및 이로부터 제조된 폴리에스테르 필름에 관한 것으로서, 상기 폴리에스테르 수지 혼합물은 압출성(가공성)이 우수하여 물성 및/또는 품질이 우수한 폴리에스테르 필름의 제공을 구현할 수 있다.
