고리올리고에틸렌 테레프탈레이트가 폴리에틸렌 테레프탈레이트의 결정화 속도에 미치는 영향 -등온 결정화-
Effect of Cyclic Olige(ethylene Terephthalate) on the Crystallization of Poly(ethylene Terephthalte) -Isothermal Crystallization-
초록
Poly(ethylene terephthalate)(PET) with different cyclic oligomer contents was crystallized under isothermal condition. Crystallization rate has been determined by differential scanning calorimetry(DSC). All the data obtained through DSC were treated with Avrami's equation. Some parameters for crystallization kinetics were derived. It was found that the cyclic oligomer contained in PET retards the crystallization rate. This finding was confirmed by observing the morphology of PET with polarizing microscope.
