도 3은 실시예 1-7에 의해 합성된 유기용매에 용해 가능한 폴리아조메틴에 대해서 시차주사 열량측정법(Differential Scanning Calorimetry)을 이용하여 열 특성을 측정한 것이다. 측정 시 온도 범위는 질소 분위기 하에서 50 ℃ ~ 350 ℃의 범위 분당 10 ℃의 승온속도로 측정하였다. 합성된 고분자들은 141~166 ℃에서 유리전이온도를 갖고, 200~213 ℃에서 결정화온도, 285~327 ℃에서 용융온도를 갖는다는 것을 확인하였다.FIG. 3 shows thermal properties of polyazomethine soluble in the organic solvent synthesized in Examples 1-7 using differential scanning calorimetry. The temperature range at the time of measurement was measured by the temperature increase rate of 10 degreeC per minute in 50 degreeC-350 degreeC in nitrogen atmosphere. Synthesized polymers have a glass transition temperature at 141 ~ 166 ℃, a crystallization temperature at 200 ~ 213 ℃, and a melting temperature at 285 ~ 327 ℃.

도 4는 실시예 1-7에 의해 합성된 유기용매에 용해 가능한 폴리아조메틴에 대해서 X선 회절(X-ray Diffraction)을 이용하여 결정구조를 측정한 것이다. 실시예 1-7에서 분자구조가 직선형인 테레프탈알데히드의 함량이 높아질수록 결정성이 증가한다는 것을 확인하였다.FIG. 4 shows the crystal structure of polyazomethine soluble in the organic solvent synthesized in Example 1-7 using X-ray diffraction. It was confirmed in Example 1-7 that the crystallinity increased as the content of terephthalaldehyde having a linear molecular structure increased.
