Beschreibung
Zusammenfassung:	The present invention relates a method for preparing an isotropic pitch through a preparation method suitable for a primitive material having contents of particular compounds, a ratio thereof, and physical properties thereof, and a raw material generated in an intermediate step. The isotropic pitch prepared according to the present invention has excellent spinning and physical properties, and thus a high strength and high elastic carbon fiber can be prepared. La présente invention concerne un procédé de préparation d'un brai isotrope par l'intermédiaire d'un procédé de préparation approprié pour un matériau primitif présentant des teneurs de composés particuliers, un rapport associé, et des propriétés physiques associées, et une matière première produite au cours d'une étape intermédiaire. Le brai isotrope préparé selon la présente invention présente d'excellentes propriétés physiques et de filature, et donc une fibre de carbone très élastique et de résistance élevée peut être préparée. 본 발명은 특정 화합물의 함량, 이들의 비 및 물성을 가지는 원시재료 및 중 간단계에서 생성되는 원료에 적합한 제조방법을 통해 등방성피치를 제조하는 방법 에 관한 것으로, 본 발명에 따라 제조된 등방성 피치는 우수한 방사성 및 물성을 가져 고강도, 고탄성 탄소섬유를 제조할수 있다.
